Yeah I did there too already and each head stud and in the middle where the cylinder meets the head. Nothing showed up. I might just go ahead and do a plug chop to see if I have any actual detonation. No high idle and not really any signs of an air leak so I’m thinking it should be fine if the...

I have a soapy water mix, I go up to 6 psi, I haven’t split the cases.

Hello, I recently rebuilt my top end with a new jug also. Right now I have a 310 main and needle clip set to middle, air box lid off, hemi head, fmf pipe, vforce 4 reeds. I have stronger jetting right now because I’m on the second step of the break in procedure. from what I have read in the...

okay, so I’ll go pick up a leak down tester today and preform one before running it again. I haven’t ran it since so tore it down and it’s still apart. The guy I got it from put a new piston in it. Wiesco piston. The air of lid has been removed. Added fmf pipe. Main jet is stock 230 size. I know...

I feel like it was done correctly, I just feel like there’s something with electrical that is cutting the spark down. What do you think as far as the video goes? I had the throttle slowly and fully to kind of show what it does.

I figured I would upload this video. It might be a simple tors issue but I really don’t know. When I listen to it on the video, it sounds almost like how Polaris limits your speed in reverse on your atv until you press reverse override. Super familiar and doesn’t sounds natural.

Also, The damage that’s on the crown I thought was damage too but it was actually just shiny spots where there was 0 carbon buildup. Hard to tell from pics. What do you mean it’s to late to do another compression test? I tore this thing down in like 20 minutes I’m sure I can get it back...

thanks for the reply. So before I tore it down I did do a compression test and it said 120 PSI. Throttle wide open tested on warm AND cold engine. Both read the same.

Hey Larry! Thanks for responding. Okay so there’s been a lot that has happen since this post. I’ve not ran it since yesterday because I decided to tear it down. The TORS system is disconnected. The wires were cut right at the base of the tors on top of the carb. When I took the carb off...

Alright, so update, got the carb on today and tested it, fine when running cool but once it gets hot it starts to bog, like bad. Do you think it’s the stator? At first I was suspecting reed valves but then it hit me (earlier it revved fine but now it’s not good even in neutral) also after...

Alright so I used to have a Polaris express 300. Great model, only thing Polaris made that was reliable. Never had any issues. Fast forward to about 3 days ago I got my first manual. Yamaha blaster 200 bored to 250. Guy that did it works at Honda on cars and atvs so I thought “I might be...
