ChainGaurd for the swingarm / Sealing a plastic tank

[runutz698]

Hey Guys well after much hunting for the proper VF swing arm I found one that is right I have one now all powder coated with new bushes fittied to the bike, The onl thing I am missing is the gaurd around where the bush goes for the chain rub factor, I do have one but it has worn through.... Does anyone have a good one of these or can point me in the right direction to get one???

Also I am wanting to seal up one of the tanks have around where the petcock goes as someone has melted the little screw lugs out, And I am now going to be running a mukuni carb so I don't need the 2 taps.  So what is the best way to seal it up as I am going to seal it for good?? Anyone done this and if so what product did you use?? I also want it to look ok aswell I am not wanting to have big glugs of stuff hanging off the tank....

Cheers
Tom

Only place I could find the swingarm pivot chain buffers was solomontesa in Spain. Jared did not have them or John at Rocky Mountain Montesa. solomontesa are a little difficult to deal with and slow but it did eventually arrive OK. I am not sure if the one I got was NOS or a replica, at least I can not tell the difference.

I am glad the replacement swingarm is OK.

Be careful with sealing the second tank outlet as I don't think you will be able to use the fuel from one side of the tank. Even the H7 has two fuel taps even though the carbie only has one inlet. The fuel taps feed a 'T' in the fuel line. Maybe you could use one of Jared's adapter plates and a plug which would allow you to go back to standard if required?

Have you had the VF250 running since the engine rebuild?

Any final verdict on what caused the uncontrolable engine speed 'run away'?

Yeah I was thinking about the T-Pce. But still need a glue or slicone of some discription to repair the tank. If I can find the right stuff I already have the petcocks and adaptors from Jared and they will work if I can get something to stick. Someone told me that epoxy will stick and they were right but after 3weeks of being exposed to fuel it went like honey and let go.

Sugestions??? Fuel Proof??

Ross, You are absolutely correct the H7 has only one fuel tap. Not sure what I was taking when I wrote that entry. It actualy has one fuel tap and two entires to the carbie . So I was either standing on my head, guessing or blowing wind from my #### or a combination of all three.

Tom, I think you are talking about the chain slider which fits aorund the leading edge of the swing pivot. The one on the swingarm you got was badly worn. Jared has them in black but is out of stock and indicated to me that he was not sure when he would have them. I got one (white) from solomontesa when I ordered stickers etc it was more expensive than Jared.

My VF has the threads still in the tank but the tank has been distorted and the two thread inserts and about 1cm around sits 1-2mm lower than the surrounding area. It is not going to seal, any ideas? It was a little problem I was putting off until a bit later.

Yeah I am in the middle of making a couple of plates for the inside using alloy. Should work a treat using 2 of jareds addapors as templates. Then it is off to the bolt bar to get longer screws.

Thanks Guys
Bike not running since rebuild yet but hopefully 2 weeks, haven't really found out the problem at all nothing obvious jumps out.

Ok here some pictures of my fix for the 2 problems, One being the metal plate for the inside of the petrol tank. The other being a my home made shain rub at a total cost 4.99 and some boiling water.

Silly Fourm going to have a few more pictures..... Cause as we are all aware with out pictures this tread is useless.

Hey Nutz, ya showing lots of initative there; workplace warning signs as side panels .

The frame sure is looking pruddy - spray painted or plasticoat?

[runutz698]

Hey Come on I sell safety gear you have caught me out, It is a good sign I think it is hard hats must be worn. But yeah it is all coming togeather it now has the correct swing arm.  The frame is powder coated thinly not done with a chopper gun like other people do...... But yeah I will hopefully have it finished soon just waiting on the final package from Jared, all bottom end is togeather and the top end is all new and ready to go so hopefully by the middle of this month. I will post a video for all to see once it is all going....
Cheers

I've been thinking of doing something similar and have been 'keeping an eye out' for a suitable plastic. Someone else on the forum talked of using a plastic chair seat base.

I'm thinking of doing the same panel you have on the VB. All the VB's I've looked at do it a little different. I like this solution.....


Or I might do the VE's FIM side panels. Decisions, decisions .

Or maybe two; one for looks and the other for racing .

[mx250]

Sorry Graeme but I think VE side panels on a VB would look pretty......EEEUUUCHH!

Generally I agree Ross, the VE looks a bit 'slab sided', but then the VB looks 'bitzy'. I was thinking more along the lines of.....


I reckon that looks 'ace' and is partical as a race bike.
