I have been motoring along using a Lifan 98cc 2.5HP 4 stroke on my DH MTB & felt like the Std Max-torque V-Belt Pulley clutch was lacking. I contacted Jim@MaxTorque & after much email correspondence & sending him pictures of my application, he advised me to send back my clutch to have the Oilite bushing that comes stock replaced with precision sealed cartridge bearings. It seems the bushing isn't great at staying lubed even if you opt to drill the crankshaft & clutch sleeve & install a Zerk fitting (Max-lube modification). He even offered to change out my clutch springs to alter the rpm engagement point.
I received the clutch back in the mail today & was very excited to open up the box to check it out. I was going thru withdrawals last week without being able to ride 'THE BEAST' since I had sent the clutch to Max-Torque for the tweaking.
Jim@Max-Torque went the extra mile. After opening up my clutch to examine the innards, he installed heavier duty shoes & stronger clutch springs for a slightly higher engagement point. He replaced my drum with the billet pulley drum & precision cartridge bearings to replace the oilite bushing. He also sent me new set screws & a slightly longer key for the keyway. He also sent back my old drum after grinding a few slots in it to better hold the bushing grease should I ever need to use it again (I doubt it) & the old shoes/springs.
I took a few pics of the clutch before eagerly installing it to get my MB riding fix. The cartridge bearing makes everything spin better & should last longer without the need to constantly regrease the bushing.
One thing I learned is that if you dont ask, you dont get.
For $40 + shipping both ways $12, I got one sweet piece of equipment.
The Max Torque website is outdated & in need of a modern day revamp (just like my clutch). They can do some pretty amazing things that aren't posted on their website, so I definitely recommend dropping Jim an email to inquire. I did ask him about centrifugal clutches made for the popular Honda GXH50QXA type 50cc engine & he makes a clutch for it with heavier springs for the higher revving little Honda.
I may need to get one of those one day.
