Nice. Thanks, mister! This was quite helpful.

Your video helped me a lot with this engine but I am afraid you might have done mistake fitting tenioner before head cover. This engine has camshaft positioned by head cover and in this scenario, right side of camshaft could have been lifted during tenionser installing , so putting head cover may lead to overtensioning chain.

Hi how i think good can u help me with my raptor 660r 2005

What would you typically see these act like if you dont follow the install procedure and simply install without checking voltage

I did this water pump rebuild and now the hole on the bottom of the water pump is pouring coolant out… any ideas ?

Great presentation…I’m a 750il driver…these are fun cars especially if you can do some work your self. Beautiful Country TN, PA, KY? I’ve owned your model a few years ago.

My 2 stroke is doing that half throttle redline right now too

Those are not phillips screws at 9:30, they are JIS screws and will strip out very easily if using a normal phillips.

Is it alot of money to rebuild these? or is it even worth it?

AWESOME VIDEO!!! No tacky gimmicks, didnt spend 45 mins speaking about non sense. just straight to the point and very informative well done thank you sir

Question. What jets are you running for the 686 kit in the carbs?

Your a real one man

them trans gears gonna chew through any dirt. Steel gears.

How mutch would it roughly run to do a bottom end as well as top end done by a shop?

I’m reassembling a 96 rn and I had to do rust removal on all the bolts for the whole bike. I had everything marked with sharpie but all my marks came off in the part wash 😅 I have most of it figured out but wanted to double check a few i could not remember the exact place for.

Found ur CZcams channel.. very good info u have helped me get very far on a raptor.. thanks for the videos!! Keep them coming

Is that pin on the inside of the crankshaft end necessary? Visible around 19:45 in the video. I’m wondering bc I’m doing a crankshaft replacement on my xr100, old crankshaft had a pin there but the new oem one does not. Can’t really think of a purpose for it either

Hello Bud I have question sir.. I have same bike Raptor 660r 2001 .. my bike is throwing out the coolant I don’t know from where when it runs after couple minutes later / I got notice too the Fan Radiator is not working as well .. so what can I do sir ?? 1- Coolant is dripping after bike runs … 2- Can radiator is not spinning ( working ) Hope you can give me a hand to find out the issue thanks

First off, thanks for the very informative video. Just curious where you got the 0.96 to 0.98 spec. In my Hanes Manual, the instructions recommend 0.5 to 1.0.

Very well explained, thanks Man 👍 I need to do this on my Crf100 and they have the same engine, Thanks again, Greetings from Canada. 👋

What is your thoughts on the piston that was included with the jug? Decent piston? They are only 30 bucks. Your videos have help me a lot with rebuilding my 660

I got a 2006 grizzly 660 I watched your video on the timing everything kind of similar in the raptor

what's that extending socket?

Great job brother. This is the best CZcams video I n raptor by far.

Any way to just changethe fluid? I have an 1978 Chrysler with low miles and just want to change fluid.

Great vidoe

I have a raptor 660 and it breaks up and back firing at a little over 50 percent would that be the main jet or the needle? Once it gets past that point it’s fine but then when slowing down it starts back fires again.

Great detail!! One of the best videos I’ve watched!! Thanks!

Thank you so much! It really helped, you explain everything really well! 😊

I have perfect idle like a brand new car, and i can do high rpms nice and smoothly but anything in-between sucks. Cant even get to freeway speed . It something that recently happened. I have perfect 53psi constant fuel pressure too.

Where can I get the same radiator ?

You made it to gas pump. That's a plus

Check engine light vacume leak ? Fuel tank fume recovery system

I know that this video is old but does the fuel mixture screw have a o ring

1 7/8 socket seems rather big for that nut. Shouldn’t it be 1 7/16 instead. Great video btw. Well explained

So my ‘89 F150 doesn’t have ANY coolant lines going to OR coming from the throttle body. Is it required, because I drove the truck exactly like this since November…😅

Very well explained and detailed video!

holy. it would drive me insane working on a wheeler that dirty lol

My rebuild kid has a metal tube that goes in the hole where the shaft come through the pump. Is there any guidance on how to remove that metal tube so I can put the new one in?

Love the videos could you tell me we're I could get the left side inner crankcase for my 660 .it's cracked underneath the jug .where it bolts down .any reason why it's gone there please. Quads are all new to me thanks again

I have a 660 but it’s not goin out on full throttle it starts easy n runs but not taking full throttle

My kids learn how to ride on a Honda XR 100. I picked the bike up from my ex-wife’s garage couple months ago. Thought I was going to go for a quick spin but the gosh dang piston was seized. I removed the spark plug, and noticed the spark plug was barely barely snug. Removing the spark plug revealed a thick crust of settlement. I am not sure what to do next. This video it’s pretty awesome. Thank you for the video.

How about the gear, is it in a neutral?

I order two different niche head cylinders and neither fit for my 03 660r also done rebuilt it to a 686. Only thing holding me up is a head cylinder. Can you please point me in the right direction on getting another head cylinder?

Thanks for the vid. Quick question. I see you have a Chinese cylinder. Is it any good?

Do you know Rember what the torque spec is for the crank case bolts

I’m trying this and man it’s all the way off. Sometimes it’s reading .000 and sometimes.561 but it’s jumping around too much to figure out. And ideas?

Why do big bore kits require case boring when the description says direct bolt on??

I’m tuning up my father in laws 2001 660r. He had a new carb on it, but it doesn’t seem to have the fuel/air needles that can be adjusted from the bottom with the carb installed. I ordered a set, but I can’t figure out the order of the o rings and washers on them. Any ideas?

Great video
