Yea Carbide #3 will be getting it first. It’s the ‘trail rider’ of the bunch. Still experimenting with the right sliders. Took the 12gram sliders out two weeks or so ago and put 10 grammers in. Since it’s larger (58.7 or 58.9 — I believe). Naraku cylinder head was installed and valve lash checked, I was only able to drive it around the block for a short while. The winter weather here lately has made it difficult to get it to the back-40 and do the prairie riding. Maybe on Saturday I’ll try.
Compression was low- but the cheap compression kit Could have been the issue also. I couldn’t use the 10mm (believe) spark adapter as it leaked horribly so had to use the ‘rubber nose’ and long neck adapter that cam in the kit. Initially I forgot to pin the throttle al the way open so only got around 75 psi BUT. j caught that and pinned the throttle open and psi’ jumped up. Motor only has 378 miles on it.
The piston and rings actually looked pretty dang good. No defects noted so I sent back the compression kit and looking for a new one made by ‘Posse’. Could really have been a bad compression kit. We’ll see. But I should be able to tell with larger head, if there’s real improvement after I get it out for a good long drive. The small drive I did take, I could tell there was a good improvement being the intake and exhaust ports are larger. It did breath better for sure.
Jetting is good so far, little rich but I’d rather have that than lean.
So if after a good test (and good compression kit) I find compression down, I’ll just rebuild to a 155cc set. It’s sitting on the bench now just waiting. If compression test turns out good. I might install on the spider.
Going to remove the pneumatic petcock and Install a on/off instead and cap off the extra port to the cylinder head . It hasn’t had problems yet but it’s a potential issue down the road if not taken care of.
Carbide #2 is pretty much bone stock but with a new shotgun exhaust, uni, jetting and 39 tooth axle sprocket. It runs fine just isn’t the everyday rider. For the family when they come out.
3203 is in storage- been concentrating on the Gy6 buggies. Runs like a champ though.
The manco is … sigh… a pain. It will be sold probably.
Spider needs some work on jetting. Great running until wide open- it shutters back and forth. No air leaks at this time though. Top end was rebuilt the other year. Just being temperamental. Needs a new fuel tank installed. Might get that done Friday.
So yup- Carbide #3 will get nano installed
