Default Trouble with BUKU clutch.

Hi guys, I have a losi 8ight t 2.0 with a clocked nova 28-5, combined with a novarossi 9886 SS pipe and 41001 header, my gearing is 15/48, and I cant seem to get my clutch set up properly I get temps of excess in the 340 range. .I truly believe I need to gear down, im using stock wheels which are 135mm. I've recently gone back to the stock clutch with a 13t clutch bell and I feel im doing a lot better. Ill give the buku another shot witj a 13t clutch bell. Any thoughts. On this? Thank! -Adrian

Use a new bell with your buku. Don't let grease get on the shoes either.

why did you bump it from a 13t to a 15t? should run the same gearing might fry the shoe's with bumping it up to a 15t
thought the stock gearing for the truggy was 13/50

You would have als glazed up the shoes from over gearing with the 15T bell, Yes buy a new bell and sand off the shoes back to the clean alloy, start with the adjuster grubscrew about a turn in from flush and set from there.

I'm not sure if you are supposed to sand them or not but I do know that if you think you got bearing grease on them you need to heat them up with a heat gun and it will make whatever residue come out. I also think you need to use denatured alcohol but I'm not 100%

Does the clutch engage correctly or slip excessively or you don't like how the truck launches?

post some pics of the shoes and the inside of your bell.

it says on the instructions that come with buku clutches to lightly sand with a fine abrasive such as emery paper which will restore the clutch shoes to its original characteristics. reading the instructions never hurts

Grease and characteristics of use...from the pictures I seen the shoes were black and full of contamination......

I run that same clutch on my truggy, with a nastier engine and the same 15th gearing with no issues...difference is my shoes aren`t black, they are brown.............. Also I ran the clutch for roughly 4 gallons on my 28 and they showed near zero wear.......... So the clutch is more then capble of holding the engine and the gearing.... I think Element is having some sort of issue with oil/grease getting into the shoes....

It's not in the instructions but Philly has posted that in order to get grease oil or fuel off the shoes you need to heat them

I just bought 2 brand new buku clutches 34mm and it is in the instructions. there is a smaller piece of paper included which clearly says to use emery paper to clean them off.

I know but what meant was heating the shoes was not in the instructions.
