BIKEMOTORPARTS.COM...Anyone Using?

[Porkchop]

I'm thinking of using one of these friction mounts from bikemotorparts. I don't to much like the looks of the side mounting engine either, but the kit does look simple and fairly trouble free. That along with the fact that after finding out about these things, I just happened to have a new engine that will work. I did not see anyting on the site about a polyurethane roller though. Maybe I over looked that part. I didn't think about stress on the frame, but I do wonder about the stress on the engine block it's self where the 4 mounting bolts go into it. I bet the aluminum/alloy block will break from stress/torque before good quality mouting bolts will ! Glad I found this thread. Thanks !

100 bucks ??

It costs me over $100 and three days to replace a Staton roller. UPS shipping also kills me.

I have been pretty happy with the Staton friction setup
but man oh man
that don't sound good 5-7 ------------ 100 bucks
and a pain in the rear
to change out roller ?

changing just the bearings would be just as hard -- correct ?

ride that thing sideways

Yes, I had read that post about the pain and the $. Does make one consider other options. I don't like having to work on things. It's different when you WANT to work on things. One of my best friends owns a machine shop. I have a Grubee 50cc on the way. I've already given him a heads up on helping ! Hee ! Hee ! He cones in handy at times !
Gotta go ! Thanks for the reply ! Oh by the way, like I said, I have a Grubee on the way. Haven't made a total desicion yet. I might keep it and do a friction mount friction drive. I'll probably do the Grubee for the time being though !

I Got Me An Idea!!

To save machinist costs, I drilled two holes straddling the bearing side of the drive assembly. After removing the snapring I use a car gear puller/steering wheel puller and PUSH the bearings/roller/clutch drum out towards the engine side.

If you have new bearings/roller/spacer/clutchdrum, then you can press/pound/persuade everything back into place.

HINT: have a machinist machine a slight amount off the friction roller's ends so it'll be a SLIP-FIT, not a press-fit into the bearing.

If you're gutsy, then machine the Staton housing likewise, so that the bearings are a slip-fit. Then everything pushes out much easier.

It's impossible for me to remove a 1.5" roller from a friction housing without paying the machinist. When I machine the house and roller, THEN I can remove/reinstall easily at home.

But it'll still cost $$ for the parts. ANNND the outrageous UPS shipping.

Well, I ordered the BIKEMOTORPARTS friction parts last night. I already had some of their parts, so I selected ala carte/piece-meal.

Using it for my GP460 5hp engine and 1.25" roller. Looking for 40mph at 12,500rpm. If the engine has more to offer I'll see if a Staton 1.125" roller/spacer/clutchdrum will fit on this BMP kit. Their 1" roller is too small for my needs I think.

This kit does have a 1.5" urethane roller as an option.

I understand exactly what you're saying. All great minds think alike ! I had actually already planned to do that very thing. Labor ? My best friend since we were kids owns a machine shop ! I've already given him a heads up on my project ! Lucky for me, machine cost is not an issue. In fact, I have helped him several times when he's in a crunch with getting parts out on time. So even I know a little about machnie shop work. I sctually find if fun and interesting. Don't know if I'd want to do it for a living or not ! Thanks for the reply !

I'm not familiar with engine you quoted. What's that ? And it turns over 12k-rpm ?
Fill me in ! I'm loggong off as soon as I send this. Will be back in about 30-45 minutes ! Thanks !

Just put GP460 into the search engine or look for anything that begins with DetonatorTuning, lol.

I'm back. Had to run some errands and took a short through the mountains in my convertible ! I clicked on the link you sent, but I get a message telling me there is no such link !
