I picked a bit of crud in the carb and the bike started running weird at low revs. As it was a hot day, I was wondering if the pilot was too lean and switched back to the factory 45 jet, but that wasn't it and i just cleaned out the carb to get everything back to normal. I left in th 45 and honestly can't really tell the difference now. Starting is similar with both.

The gearing change is excellent, I'm kind of wondering why the bike isn't like this from factory. My dad now has a Beta Evo with a slightly lower first gear and is quite comparible in low speed maneuvering. Highly recommend chaning the gearing on the GG.

Venom purchased on Amazon. Front is a bit iffy on the Grom and I modified it. The rear is perfect on the TST spools.

That's a nasty fall! I have a flywheel weight and low compression head on the way, but I've been very happy with the gearing since changing it. I don't think it needs to be lower than the 10/42 now. What I've found is my clutch control has improved and I can easily control the low speed now with the 10/42. The goal with the low compression head is easier starting and smoother running with our lower octane fuel here in Canada.

The Yoshimura high mount exaust was not available when I got the Tyga. I can't compare the sound, the Tyga is not overly loud though.

@@RC-Engineeringstill happy with the Tyga? I’m thinking about placing the order

Excellent quality, and a great sound. Without a dyno it’s difficult to test true performance but I felt a good difference when combined with the intake mods. I highly recommend it.

I ordered directly from Tyga. Shipping was reasonable and very quick.

I ordered it dofectly from tyga too feb 27th but my order is still pending . I ve emailed tyga several times butbi cant get a response. Does your paperwork have a phone number that i can call? Thanks for responding

The carb was jetted per the manual (page 118-119). Also the manual suggested weights seem spot on (page 38).

@@RC-Engineering When I bought the bike a year ago...I looked all over for online manuals....looks like gasgas finally got it together. 👍

I used the existing master link and added another, but also need an inner link to connect them. I could have used a chain breaker on the link and a half I bought for the I net link, but I had an inner link on hand.

I was just being an ass i saw what you did all good 👍

😂😂😂

How is the angle and chain wrap near the front sprocket clip? I looked into it, as can be seen in the calculations, but ultimately decided 10t was already on the small side and changed the rear sprocket.

@@RC-Engineering I was a bit worried about that but the Sherco 125 I have has 9/42 gearing so I figured a 9 tooth front sprocket would work. It's a tighter angle, but no issues clearing anything. It was a quick change out.

Great info, thanks for sharing!

Just so you know, most people in Spain directly switch the 10tooth standard front sprocket for a 9tooth, specially for section riding. Myself included. No problems whatsoever✌🏼

Thanks Jack! Next one will be about getting it to start better, that day took a lot out of me, lol

Thanks! I changed it at 7 hours. While not very dirty, the sump magnet was full of small filings. As a bonus hidden gem on the bike, the fill plug is identical to the sump plug and also has a magnet! That magnet had some much larger metal splinters on it. I was pleased to have both magnets clean even if the oil wasn’t desperately in need of change.

Ouch! That’s a harsh start with a new bike. 😢 Before I rode the bike, I went over it carefully. Removing the airbox, wheels, tank and more, I carefully went over electrics and cable routing. Everything was fine, but I’d heard about the throttle potentially being an issue at the throttle body. After carefully going over it, I didn’t find any issues. Also, since I was very young, I always snap the throttle before starting. It has to return effortlessly or I won’t attempt to start. Not sure why I developed this habit, but I’ve found a couple times through the years where I needed to investigate before starting.

Thanks! I’ll change oil before next outing 🙂

I haven’t noticed! Mind you, I’ve only been practicing low speed and maybe had it in 5th 2-3 times. What I have noticed is that shifting is a deliberate effort compared to my other bikes, but I put that down more to the shifting geometry with lever shape an of course how far it is from the footpeg.

ive got a 24 model and yes it does still crunch if you don't let right off between 4th and 5th.

I'm guessing it has to do with switching out of 4th with it's multiple-engaged gears to a significant jump in ratio to 5th. One of the disadvantages of the 4+2 configuration?

@@RC-Engineering I don’t really see it as a massive disadvantage. It’s a trials bike. 1 to 4 are the only gears you would use in a section. (It’s one massive bog if you’ve got up to 4th 🤣😂). Then 5th and 6th are only used on long runs between sections. And once you get the knack of rolling right off the throttle going from 4th to 5th it doesn’t always crunch either. Just most of the time. 🤣😂

oh and i use the tst worx industries ram airbox cover. overpriced piece of plastic but it looks very nice and factory.

I’m really pleased with my setup. The intake mods with the Decha tube and modified cover seem to be an improvement. Combined with the high mount Tyga exhaust, I’ve seen a significant gain in overall performance.

​@@RC-Engineering dont forget the ecu flash, the motors come running lean from the factory due to emissions which is why airbox was so choked off. The ecu will not be able to see the new amount of air and less restriction due to the lack of wideband sensor (02) and with same fuel trim and more air youll run hotter than stock!!!

lol, thanks. I might have considered the new Sherco/Scorpa, but it would never be at the price I got the GG for. The more I learn about it, the more I’m loving this TXT!

For weatherproofness. I intend on riding year round and need the bike to be ok in rain. Plus I ride on dusty road at times and need that protection too. So far no water issues and even in heavy dust the air cleaner doesn’t see much. Happy with this setup!

Thanks Josh! See you out there :)

The Noble radio (regular and Pro) is BOTH left and right. When you take it out of the case the wheel is pointed away in the center and you need to rotate it to the side you want. It's "stiff" to rotate so it doesn't move when using it. It also means that you can adjust the angle you want, being able to offset like other brands need plates to do. When you look under the screen, there is a protractor to show the angle you have it set at to easily set it back at that angle every time. Quite a simple and smart solution :)

Hi John, much appreciated! While latency is important, there is more to the feel of the controller. How the A-to-D and D-to-A converters handle the info stream is the major influence. Sanwa has typically been a leader in this (explains why many pro drivers that don't have a radio deal choose Sanwa). The purpose of the test was to see if I could detect a difference and I was pleasantly surprised with the results. Sanwa is still great but it's also good to see the Noble Pro is a real option, especially at the price of their receivers.

Great quality video by the way!

The ECU has maps it choses based on sensor readings. It also has trims of the parameters in a map, so it can best adapt. The map and trim is adjusted as you ride and not selected instantly meaning it will adapt slowly as you ride. With major changes like intake and exhaust, it will take a while for the ECU to best adapt and will be “caught up” with the mods.

Ok I see. I’ve heard of people tuning it using the ecu. So is that just because they want instant adjustments?

That's ECU reprogramming. They are changing the maps to give better performance and target the mods they have made. The stock ECU is mapped around great fuel mileage, but performance often sacrifices fuel mileage. It's about balancing personal priorities.

Thanks! The only motor mod at the moment is the intake (czcams.com/video/GJWvHy_UEW8/video.html). ECU flash is on the list of future mods, especially with the improved performance with the intake and this exhaust.

I'll look into the air cleaner. Testing on the CRF300L one showed it wasn't terrible when clean, and it's the same size as the Grom one. But that doesn't mean we can't make it better, right? The exhaust video is up (czcams.com/video/N0J1jLwR0Pc/video.html), no ECU change yet but it is on my list of changes!
