That mark's no worry, you better pay attention to the oilpump's housing - does it measure correct (according to the workshop manual)? Looks worn if not machined, better make sure it's all (rotors too) good still.

compression loss

Post  temporary kiwi on Thu Nov 12, 2015 10:08 pm

just noticed the nice job your machine shop did on the combustion chamber, however that also means you could have lowered the comp ratio, thats if your using the std piston, a hi-comp piston will rectify that and give you more grunt

Thanks for the comments, sorry I was lazy this winter and I didn't work on my bike so I started to work back on her late this year. I got the engine all back together, I did use the Stock piston since I wasn't sure about the HC one, well I will see how it feels with it first, if I have to change it later on I can do that anytime. Something to do to my piggy LOL! The only thing I am concern on my rebuilt is I have an extra washer laying on my working bench which I can not remember where this could be left behind! I check carefull all the manuals picture but I can not see I missed it! I hope it will not make a big deal out of it!.

I would prime the oil filter and kick her slowly over by hand with the de-compressor in to make sure oil is everywhere, I think some even crack the oil hoses to make sure there is no air trapped.

I think the popping is normal...just un-burnt fuel being sucked through and then detonating in the system.....my 1300 pops like man on de-acceleration specially after opening her up first.....wakes the neighbours lol

What elevation do you mostly ride and what is your current jetting?
i run from sea level too about 500' open inlet, hrc tip, 68s pilot, b53e needle middle clip position, 172 main, fuel mixture screw 2.25 turns out from lightly seated and she pulls hard all through the rpm range has very minimal pop on decel

i have read on other sites that your pilot or slow jet as some call it may effect popping on decel and may need ti richen up the mixture via the fuel screw, but it took me a while to finally get mine to where she runs nearly perfect all through the rpm range being a little rich than lean

Toronto sea level is 76 mt and I can't remember but looks like I have the same set up like yours, I will have to double check , she was running nice last year but I went eith a HRC cam with the rebuilt and open up a bit the head port so for sure I will have to re adjust my carb

I haven't bother to check mine in the last 4 years like Mauser! Lol! I wouldn't bother but that's just me! It doesn't take much if you feel safe doing it go ahead and do it.

Time to switch to Fully Synthetic oil?

Post  bikerman on Sat Sep 24, 2016 2:52 pm

Hey Guys,
I want to change to fully synth oil, I know Burrp was saying some brands like the shell helix but is this car oil or special for motorcycles? also is too early to switch or should I wait a bit more?
