I found me a 1990 mbk 51 frame from Dos and plan to make this much deserving bike pretty. I stripped it down and degreased it and went to work on the tank
Dos soaked the tank for me and after shaking the heck out of it with some m8 nuts I was able to get all the chunks of rust out and get clear water to flow through. I dried it out and filled it with premix and called it a day. Will probably clean it again later on down the road
Here it is with a front end mocked up
The forks are 33mm paioli from a ktm65 and the wheel is a kx65. The triples didn't fit but some from an old it or dt175 fit perfectly. I'll need to use mbk cups and bearings though and maybe shorten the forks or put clip ons above the triples.
I have clip ons on my pug and because the seat is so low below the bars they are pretty comfy.
I also found a new Tokico dual caliper for super cheap awhile back that'll work with a bracket fabbed up.
I'm having trouble taking the swingarm off. I have a square swingarm I'm gonna use but the original is frozen solid to the bushings. I tried pounding the bolt out after repeated application of penetrating oil over the last few weeks but it won't budge. The swingarm moves freely but the bolt won't move. Maybe it's bent?
Any suggestions or tips from anyone would be much appreciated. Maybe heating the bushings or I could just cut it off since I won't be using it anyways. Seems like a waste of a perfectly good part if I hacked it off.
I am trying to decide what to do with the frames finish. It's a pretty neat looking champagne-y color or maybe sun faded white. I would leave it alone except for the rust.
There is more rust behind the seat mount area and behind the side rails so I'd like to do something to avoid problems later.
I'm waiting on the engine bits so I would like to make it look nice before I start assembling anything. I have the new Doppler clutch pulley and a giraudo repop variator reserved and coming, along with a bunch of other stuff to build up the engine. Fun times ahead.
I am going to be welding some common frame reinforcements soon but need to research gas tank welding safety before I put a torch anywhere near that area.
Tips to avoid an explosion are gladly accepted.
