Yes anything bigger that 44.4 usually is considered a Stroker

I use a variety of gears depending on what pipe I'm using and what distance I'm racing at. Every motor is set up diffrently !

Haha yeah it's slow 7.9s@82 1/8m 13.5@92 1/4m Anytime you want to post your time slips , please do! I'm sure the world wants to see.

That's the best way to tune your timing curve :) I use jiso and a few other boxes that are similar .

Gear oil :) but I would assume engine oil would work. It's easier to use the gear oil since your going to use it :)

Aloha!🤙

nice trick! 👏

Better flow and breathing of fresh fuel mix. A Honda block is very inefficient in flow, a terrible design.

That's awesome, how deep roughly did you cut? I've got a couple Sym dd50 engine I'm going to cut for 120cc

Once I get it back running it will be lol!! Thanks !!

Hahah I need to make it go faster!!

Yes it is ! I just repacked it for him. It was so dam loud hahaha

Spree frames are always fun to build! I have a spree smile as well that I built many moons ago. Only issue I have is the ride is harsh lol! Hurts my back!

I try to target around 11.8/12k anything more it doesn't go faster it's pretty much piss revving ;). Drag strip tuning and street has its similarities but it's way more different than many think. You have a set distance from a dead stop to go as fast as possible unlike street roll racing it's a total diffrent style of tuning :)

@@n4smotorwerx you running 1/8 or 1/4

I have run both , usually just fool with the 1/8 since the 1/4 takes a diffrent time and gears .

Thanks and Aloha!

Yes, sir! I prefer to use that crack over the 44 just because the timing is a little better. You might have to trim the base of the piston a little bit for clearance on the downstroke.

@@n4smotorwerx I think that I want to get the 43.2 and the athena 72 and I won’t have to trim anything

Yes sir!!

@@n4smotorwerx nice.. thank you

Thank you 🙌

😎😉

I always love using a mini stroker crank with a Corsa set up, it creates a little more torque, which really helps for going up heels and also if you're a little heavier of a rider

So the stage 6 top sits straight back , if you use a Twh one , that has a slight outward angle. All my intakes I had shape . Again they are all a copy of a copy. Stage 6 is a copy of a KRS or koso racing . The others are a copy of a CT brand

@@n4smotorwerx ok thank, you next engineI I'll try the TWH, hope there is no filling and shaping needed

Aloha Nick, I got up this morning and thought that I should tell you that you could use a chrome intake top with the stage 6 reeds :) I know they stick out sideways and they are cheap to get! Hope that helps!

Does it need to be shaped inside or is cylindrical inside? I thought I've read you are not a fan of the chromed one. Mahalo

Honestly they all are the same. China made, even stage 6 is China :) Main thing is to check its flatness, because they are all not truly flat! Major causes for air leaks especially the Stroker ones . I don't use the chrome ones because they are made really cheap and they use a 3 petal reed which I dislike:)

@@n4smotorwerx I reply to another of your video

My own.. I used diffrent parts to make it work

Hahah!! It's a case splitter tool ! Cant be pounding on cranks!

​@@n4smotorwerx I'ma need to look this thing up lol. I can't tell by looking at it if I'm not understanding the mechanism or because something isn't right and idk the thing I'm just confusing myself into a circle lol.

​@@n4smotorwerxoohhhh ok It separates the halfs that makes way more sense then me wondering how this thing is going to spin lol

Yeah you don't want to pound on any crank unless it's broken, stripped , throw away!

Stock carb, 85-90 jet

Yes they do ! Contessa is the non race version of the Corsa

@@n4smotorwerx thanks but it fits nicely in the af 16 engine without new crankshaft? because I've seen some videos where they upgrade the af16 engine from 50cc to 70cc and don't put new crankshaft

Most people will upgrade the stock crank with a aftermarket , but if your on a budget the stock crank will handle :)

You can used af18 parts on the Sym block

Won't work, 54mm is designed for a 52.6 crank. You still need to cut the bore so you might as well cut it for a bigger crank too!

@@n4smotorwerx Ohh okay. Then i will ordar a twh 50mm cylinder with a 44mm crank. This is good or not?

52.6x56mm

@n4smotorwerx Thank You... I've been watching the drags with those scooters... its insane!

It's just fun things to do :) Cheaper than building a car lol

@n4smotorwerx yessir... I'll be building a custom chainsaw, using the DIO cylinder, head, piston, crank... Reeds and either a Mikuni, Keihin or Nibbi carb... then I'm onto building another racecar. Lol

Custom made

43.2mm Twh mini crank

Hit me up on my FB or IG !

Gearing all depends on the distance your using it for ;)

Came with the tool :)

lol you should have seen the time the throttle got stuck and I flipped over haha No video :( if I had that I would have posted it !

@@n4smotorwerx bro, that kind of reminds me of Rich from Pinks lol. He was looking all “bad ass” hopping on the motorcycle and then totally whipped out lol

I seen a help build a few for low rider bikes before :)

You carefully cut up your old mount :) The shock strut is a 1in thick walled black iron pipe. Over kill but that's all I had around the shop

@@n4smotorwerx is that 1 inch od or id

This head set fits with the correct handle bar :) you can also relocate the tabs on the stock bar to make them work as well!

@@n4smotorwerx sounds good , appreciate the help sir

Anytime! It's a lot easier to find the head piece than the correct bar. Relocating tabs are easier if you can do them!

😎👍🏻

Thanks and Aloha!

It's running like a champ! Not built as a fast roll bike! Still needs alittle tuning but it does 70 pretty easy with this pipe :)

Couldn't agree more! It's one of my favorite builds for my customers !

Just finished up the porting of the Corsa today :)

@@n4smotorwerx when will be the upload? Looking forward to it

Yes it is!
