Willing to ship to Australia? Do want.

2. The updated cam chain tensioner button that kitaco sells can be had for like 10 bucks form franco, or hell go down to your local hardware story and grab a 20 cent nylon bolt and round off the head and use that... (thats what i used for the longest of time)
3. never in the history of the grom has the actual arm of the tensioner broken or bent under normal use within the motor. Its the wheel that goes bad which the OP remedies which the kitaco one does not as it looks to be the exact same wheel as stock.
Needless to say the kitaco unit makes me yawn... it doesnt fix the problem of the chain sliding on the wheel as its not toothed. The finbro one does as it has a slightly toothed setup but it still rubber (not going to be good for high revving 4v setups) BUT the steel wheel with full teeth like the OP's is THE answer to the problem, full ball bearings etc. Throw in a good tensioner rod button and you have a bulletproof setup.
sorry kitaco, you missed the boat on this one. do a v2 version of the arm with a toothed gear and a bearing and that will fix the actual issue. until then we will do it ourselves. admittedly, the arm is nice and the fact you can remove the wheel is good. what is the OD of the bolt (TENSIONER ARM SHAFT) that holds the wheel on? 10mm?
