I have a 4 stroke kit as it comes from Bikeberry.
right now, i'm having a few problems that i would like some advice with.
a little background first. i bought the kit a year ago in 2015. i first tried to assemble it then and ran into issues with the rear sprocket, the chain stay mounted chain tensioner, the wide crank set's compatibility with my chain, and the air filter cover. it has since sit for a year as i elected to pay off the affirm loan before ordering more parts.
1: i don't really have a rear drive sprocket option that seems to work for me right now. the stock sprocket doesn't exactly fit my rear hub and doesn't sit 100% straight and the minor wobble left still knocks the chain off. i can widen the ID of the hub hole on the sprocket, but i was looking at other options. I ordered a BBR tuning sprocket with the standard 1.52" adapter. i made the mistake of ordering this sprocket assembly as my rear hub is actually pretty thin at .624". really stupid mistake.
I was looking at getting a different rear wheel, but my mental energy is kinda running out on that one. may just go with the BBR wheel assembly available on bikeberry.
i'd just like some advice on what i should do here, from getting spacers for the hub to selling mine and getting one that would actually work for my hub.
2: I ordered a sprung chain stay mounted tensioner and a sprocket upgrade for it to try solving the problems i was having with the stock tensioner and idler pully. but i have been reading on this site that frame mounted tensioners are never any good. what tensioner for this 4 stroke engine should i have bought? i know about the motor mounted ones for 2 stroke kits, but i haven't seen any for these 4 stroke motors.
it doesn't help that my chain stays are not parallel to the real wheel.
3: after some filing to the crank sprocket, my chain still doesn't really fit. i'm going to try to file down the teeth a little as i have only filed off the burrs and flash from the edges of the teeth like on the motors drive sprocket. the bike im mounting the kit to is a +-20 year old huffy mountain bike. i bought a new chain for the human powered drive train just to make sure that its not fitting because its just old.
4: the motor kinda barely fits in the frame of my bike. well, it doesn't really fit, i have to take the cover off the air intake to get it to fit. Is it OK to cut the cover to fit around the frame or can i just place some tape over the filter so it stays in (leaving a ~1/4" slot uncovered at the bottom)?
so, yeah, those are my grievances right now. thanks to anyone who read and is thinking of advice for me.
EDIT: i found a website called maniac michanic, mmbikeparts.com
i talked to them and even though i mistakenly bought a copy of their parts, they were still friendly and helped me out. i was able to order a bushing that adapts the BBR adapter to my small hub size and their chain tensioner that mounts to a fender screw hole and anchors to the chain stay. i'll update if those parts work for me.
