There is it's the pull start. Don't have it on now
So there's no flywheel cover for the engine?
Not the good kind ?I say leave it shiny ?
?And the kitchen sink lol
Like 2mm on each side. I plan on getting it done and ballanced and trued by a professional not me. This is what I wanna removeIs say depends on how much material need to come off
I have read that guy using dremil on crank cases to get a con rod to fit. its ballanced so would not mess with them..........what a nightmare
U know what I'm saying? The crank is such a b!tch!!! Was battling crank probs since I got the alx case! First trying to figure out what crank to use, buying the wrong one, con rod issues for like 2 months, Jesus I can't wait for this crank to b sorted. After that it should be easy, well that's what it seams like, but u know how that goes ?What a ball ache
But can't quit, gotta keep pushing forward. Not tryna quit half way through, nah nahU know what I'm saying? The crank is such a b!tch!!! Was battling crank probs since I got the alx case!

Now you know why the complete engines are so expensive lol. Idk if the time and problems are worth the savings of building one yourselfU know what I'm saying? The crank is such a b!tch!!!

I'm not sure either but I'm half way in and no quiting now!Now you know why the complete engines are so expensive lol. Idk if the time and problems are worth the savings of building one yourself
Yeah I'll give them the rod and Cran and case to make sure it's good. Thx ,? there's a couple machine shops near meYou'll be fine to remove that off the crank. You'll need a lath to do it. And you will want to give them the rod too. I doubt -2mm is as accurate a measurement as it should be. There should be a side clearance spec for the rod to crank. If you were here in the states I could reccomend the perfect machine shop but they are a little on the pricey side.
well this is the crank that does fit but alx either moded the crank, modded the rod, or has a custom rod. my problem is it fits but i have wayyyyy too much play on the connecting rod/ piston assembly so i have to fit a wider rod and the only way to do that is modify the connecting rod (not a fan of that) or modify the crank. modding the crank I'm pretty sure wouldn't weaken it but probably will make it unbalanced, tho i am getting it balanced and stuff. it should be fine but i trying to make sure it wont weaken the crank. ive talked to one engine builder (forgot his name lol) he said it wont weaken the crank. that probably didnt make any senseI might be missing something here but why not just buy the crank that fits the alx case?
Good question. Mostly a guesstimate, this cyl was dynoed at 17.39hp on a scooter, soooo I'm going to be running e85 which add alittle, also don't forget to remove drivetrain loss cuz rcs have wayyy less drivetrain loss than a scooter. A scooter has about a 5% drivetrain loss so add that. When I first run it, it will probably "only" make 12hp cuz I'm using a small 19mm carb, once I switch to a 25mm it will open it up alot. I'm Hoping for 20hp, seams realistic to me but I could just be delusional lol that's the Dyno sheet for the cylinder. Mines the red line, mk1. This Dyno sheet is for a rebranded 1. They now have a mk2 but it was out of stock.Just wondering, how are you getting these hp estimates? Or is this just a guesstimate?
