One I worked on which is a 69 cm90 I think
lifan 125 semi auto

the rear sprocket used 4 bolts and nuts to tighten to the hub
those kept coming loose, and jamming up the wheel from spinning
pretty hard fix on the side of the road, and very dangerous if the bolts didnt bend and slowly jam it to a stop

im pretty sure yours uses the same bolts to mount it
I ended up tack welding the bolts and nuts as even replacing them and using loc tite they still vibrated loose

alot of parts on that bike started to vibrate loose when riding it
and it barely seen any road time

I suggest every bolt, and nut be loctited, and if you can safety wire and cotter pin
at those high speeds things start to work their way loose

I hear you Mike. I've owned thumpers before XR250, last one was a KLR650 - every damn bolt would come loose on them. I've heard about the rear on sprocket on the C70 needing to be tack welded with bigger engine running.

I've found routes from our place into town without the need for high speed - not the most direct, but I can make it work. Most likely I will wind up flipping this thing for something with a bit more power unless my youngsters really take a liking to it. We live in a semi-rural subdivision outside of Austin - 3-15 acres lots, creeks, trails, etc...so they will probably have ball for a while until they start asking for dirt bikes.

Installed the 3.00 Gazelle on the rear today. My gut tells me that additional rolling mass is definitely affecting the pick up and the uphill speed.
Just one very short ride on it, but that's my gut. The 3.00 is a tight fit, you definitely have to center the wheel or you'll get some rubbing - naturally you want it centered anyway.

Mike, unless I'm mistaken, my C70 has some locking tabs that keep the bolts from moving. I should have taken a picture when I had the wheel off. I'll see if I can get a pic.

Compare

Definitely a better, more aggro look.

yeah that cm90 I worked on had the fat tires too

maybe the newer models have that locking tab on the rear wheel nuts
the one I worked on was 1969

I went with the 2.75 up front. You either have to drop that little plastic fork crown cover or trim it unless you like the tire rubbing it.

Front compare

Looks much cooler with the big rubber

With her clothes back on...looks pretty good...

New tank arrived, it is in good shape. Installed.
Image

Bike looks a lot less death trappy with the actual tank in it. I pulled off the front turn signals off. I plan to put a couple of mini round flush mount lights there.
Bike is starting to look a bit cooler. I need to do something about the seat, the bog stock seat looks funny on the chopped fender.

there are single length seats available
my friend had one but to me it looked too short
I suppose you could chop the pan down and make the seat the exact length you wanted too



did that tank have a fuel sender in it?

I could have sworn I replied last night...

Agreed, I think they look odd - the short ones.
Thinking of cuttting the pan/seat, shave the height down and reupolster it.
It does, but not finding a gauge I like.

I acquired a couple more Hondas y'day...not exactly minis though, two 87 XL250Rs, 1 a registered great running bike, the other a "parts" bike, but it looks pretty complete and even has a new jug, head and cover to install.

Yeah?! I was wondering that too. It looks like it's got a fuel gauge installed on it. I didn't know they made those!
