Re pipes - my bike has the nickel plated pipe on it. Does that mean there is no catalytic converter welded inside?
I notice that if you tap my pipe with a spanner, it makes a 'thud thud thud' noise, whereas if you tap the stock pipe on my mates YZ it makes a 'ting ting ting' noise. I had always assumed there was an extra lining inside there. Re the compression tester - im pretty sure it is accurate. I have used it on other things (cars, other bikes, chainsaws) and it reads as expected. The most recent example of this was when I was rebuilding a Mini 1000 motor and it read 160psi on each cylinder which what I was expecting. I will test my bike again once I have done the reeds, as if these were leaking (which they are) it would effect compression to a degree...not sure if it would effect it to the extent of losing 40 psi though. If I cant get the compression up...would you say that 120psi is too low? It seems very low to me. |

I've ran with chipped reed petals and it made the bike a pig to idle and a bit crap right off the bottom. I wouldn't say it felt too bad under heavy throttle.
I'd be trying to run a length of wire or the likes through the pipe to see if their is anything in there blocking it. Cat perhaps. |

Yep. It was taking a good 6 or 8 kicks to get the reading stable, then a few more after that for good measure. I was doing it in sneakers too and my foot was killing me after doing the test 6 times! I had to use lefty for the last one.

I've never heard of a nickel pipe with anything in it but who knows.
Reeds could be missing & you'll get the same com reading at kick over speed. so without re reading the last 3 pages; when did you last look at the piston & check the rings not worn or snagged over? |

Piston and rings are brand new....have been on 2 approximately 3 hour rides on them. They went in fine and the piston is DEFINITELY installed the correct way - I have done this job before and checked a million times.

Cleaned the carb recently? Sounds like a blocked jet, or could be a loose electrical connection somewhere.
For me, one of the female spade connectors on the coil was loose and made my bike run rubbish, squished to a bit and its been fine ever since. |

The carb has just been rebuilt by RB designs...its definitely not that. The bike had even less power than this (substantially infact) before I did the head, carb and carby.
Is it the compression? What sort of readings have other 300 riders gotten with their compression tests? "Just wanna say thanks so thanks :-)" No worries! |
