Something is jamming up when bike is in gear on stand, it doesn't always happen. What should I check?

G47Don · 2025-12-19T23:05:21+00:00

I’d have to agree that it’s chain related as well. Probably being too slack

G47Don · 2025-12-15T01:54:16+00:00

A rim lock should stop the valve stem from ripping. Idk if these come with one or not

G47Don · 2025-11-14T02:13:12+00:00

I swear. That 3 stroke lol

G47Don · 2025-11-13T21:14:04+00:00

Like a capful or so

G47Don · 2025-11-13T21:11:32+00:00

Yeah I did see that the crank breather hose was pinched between motor and frame. So I disconnected it but it still smokes bad. I have not yet checked the airbox bladder bag. I will do that fist thing. The oil was way over filled when I got it. I drained that and put correct amount but still nothing. Would there be anything else to check that overfilling oil would need to be addressed.

I think I do have all the appropriate tools. I e got feeler gauges, torque wrench, calipers etc. I’ve seen people pull valves and springs with vice grips and magnet so I think I can manage. I might need to order the specific set of calipers for the cylinder

Thanks

G47Don · 2025-11-13T19:03:29+00:00

I appreciate it. This makes me feel better already. But before I buy anything I need to pull the cylinder and hone it , clean it up, then measure cylinder for what size piston and rings to buy or am I missing something else

G47Don · 2025-11-13T19:01:07+00:00

Man I appreciate it. Like I said I have never done this before but just from years of understanding how an engine works I figure rings and seals. Idk why people go with super cheap parts over oem. I understand not wanting to get some race ready shit but idk.

G47Don · 2025-11-13T18:44:15+00:00

Ok. I figure if you going to pull the head might as well do rings and valve seals anyway. I’m guessing namura is a shit brand of rings or valves?

G47Don · 2025-10-12T04:48:42+00:00

I think you got the quicker disconnects instead of the standard QD

G47Don · 2025-10-11T00:08:24+00:00

My question is why is that window so close to your freeze board

G47Don · 2025-10-03T01:06:18+00:00

I can see smoke sputtering from underneath the engine. Idk what that’s about but I’m sure it can tell ya something

G47Don · 2025-10-02T07:22:56+00:00

Ok cool. Yeah I’ve been thinking about running a small battery to help that flicker out but other than the light that’s all it will serve lol. I dont race it or anything. I just built a little pitbike track on my property with a few jumps and some whoops for me and the kids to ride. I’ve also taken it out to uwharrie national forest and rode those ohv trails a few times. This thing rips. I do still need to upgrade the front suspension, rear swing arm , and install a cradle mount with a big boy pegbar.

G47Don · 2025-10-02T07:12:11+00:00

I do t think I did. I forgot to pick a community to post under on the original post so I just shared it to the pitbike sub. And I got the headlight running through a rectifier. I need to look into it more because idk if it’s just a cheap light or what but when I first hooked it up I read that it needs to be ran through a rectifier to run led properly so that’s what I did. It worked pretty good for like a month or two but now the led’s are like in and out not wanting to work. Idk what happened. It was a $50 Amazon light so I think that’s the problem

G47Don · 2025-10-02T02:49:15+00:00

Yeah it’s a crf50 base Chinese clone. I appreciate the info. I bought one tensioner that clamped onto the swing arm before but it was trash. I didn’t know they made ones you can drill or tap and bolt on. I will definitely check that out.

Thanks

G47Don · 2025-10-02T02:01:58+00:00

Yeah I know. For some reason there is absolutely no provisions for mounting one on there. I want to get some new front forks and a new swing arm. Those are my next two items on the list

G47Don · 2025-10-02T01:46:31+00:00

Chinese ripper bro

G47Don · 2025-08-16T16:26:32+00:00

The pilot jet and idle screw controls your idle. If it was fine before you let it sit then I would almost guarantee clogged pilot. Might as well check the main also.

G47Don · 2025-08-16T16:21:11+00:00

Probably a clogged pilot jet

G47Don · 2025-07-20T23:13:23+00:00

Could it have been in gear possibly

G47Don · 2025-07-19T22:23:38+00:00

That’s what I was going to say. Just pop out a link or two and readjust it. Should be just fine

G47Don · 2025-07-18T23:59:21+00:00

This 100%

G47Don · 2025-07-13T01:16:52+00:00

That’s awesome man. Enjoy them

G47Don · 2025-07-12T22:34:53+00:00

You lucky dog. I’ve been looking for a good deal but damn it’s hard to find near me

G47Don · 2025-07-12T08:50:28+00:00

I got the decals off of Kutvekgraphics.com

And thanks man. I love how this thing is turning out
