Hi guys
Off the top of your head what psi are you getting on compression test?
Thank you! -

Thank you!wrote on 11 Aug 2023, 21:57 last edited by SpookDog 8 Nov 2023, 23:04Never done one on a two stroke bud. Why do you ask?…
I gather it’s different if you have the power valve pinned open or not. I don’t think that there is a definitive standard to gauge a ‘normal’ from…

I just got 140PSI on my Cagiva raptor. Did it on Sunday purely out of interest.
But this engine is worn and I'm just in the middle of a rebuild as we speak.
That said, 140PSI is good for a two smoke.

Perfect thank you everyone

Yep, the 2T pump lower 4mm screw/bolt hole goes all the way through to the nylon cog on the inside…
Plugged it with a screw/bolt…Oil & brakes? Who would of guessed?

Only thing is that the right side indicators have stopped working along with the indicator dash light. Also got to wait for PJME to get the crank in stock. Always something on a 35 year old basket case, eh?
Also got the new headstock bearing half way on and it won’t budge!…

First one I’ve done on dtr though I did one on a kx and the tolerances was so tight it didn’t work I had to get a tube that fit over the stem and onto the inner race and long enough to clear the top and few taps with hammer got it seated, wouldn’t damage the bearing as all force was on the inner race -

Lots of little spring-loaded leccy contacty things inside them, it's a harsh environment for a switch. Good post-jet wash routine to get into

gonna investigate it some more today…I had it in the freezer for a few days! It was so cold wd40 was freezing on it into slush, couldn’t heat the bearing though. It has the bottom rubber seal fitted into it. Never seen one like it before…
Gonna have to find a steel pipe

It’s been bugging me forever since getting the bike! The headlight runs off of a/c directly from the stator coil, but the brake light is run off of the battery, it shouldn’t affect it! The only thing I can think of is that they share an earth?! I’ve just rigged up an earth to the frame straight from the battery. I’m gonna see if that helps any. The neutral light looks stronger anyways, as is the PV on the key
…Fixed the indicators (& intermittent speedo bulb). Six new bullet connectors behind the headlight!! (& 1 bulb) The last couple years have been hard on the loom! Everything looks brighter on the battery now
…Almost forgot: This may sound stupid, but: 2T oil from the exhaust ‘filming over’ the battery top, could it diminish the output amp/voltage? Mine was coated and the power valve & neutral light had gotten ‘sluggish’. It’s better since cleaning, but I’m not sure if it was this or a poor earth to the battery? I guess I’ll try not connecting the earth, later after night testing…
I wish I knew a motor cycle electrician/Wizard

@HOTSHOT-III
I can remember bringing it up but not if it got resolved in any way. It’s just gotten more noticeable the last couple nights I’ve ridden. Plus my electricals have gotten gremlins the last couple days…Oh yeah! My brake light just blew…

Presumably they don't dim once the RPMs are up?

Unbelievable! Half way on a commute I’ve lost all power to the indicators, dash lights, ect. The AC to the headlight, tail light and dial lights is still there. If it was the battery I’d still have working indicators, ect, when the engines running wouldn’t I?…

Yeah, that doesn't sound good! Have you blown the fuse?

I think it might be a weak earth. There was this ‘trick’ we used to do when water cooling PCs. The 12v fans were too loud so we would wire +12v to the fans positive and wire +5v to the negative. This would run the fan at 7v so it was quieter. Maybe something along these lines is happening?…

Time to strip & clean the PV!…
