They are fun bud especially on the twisties

[Sean91]

i dunno, being 2 stroke it can be more twitchy in the corners and mine steers quite wide (although the little wheels probably have something to do with that ) not that im at all bothered of course

What tyres are on it ?
i had standard wheels on mine , i ran avon gripsters or knobblies and it was loads of fun you could throw it into bends

[Sean91]

They're Bridgestone battlax

[jompy]

S20's , 016's , 023's ? ?

[jim157]

Bt90's by the looks of it.

[Sean91]

Bt90's by the looks of it.

Yep, BT090's

i debated the idea of removing the exhaust and giving it a bit of a restoration for a while, you can can see rust towards the top of the pipe where it bolts onto the engine but it was quite well hidden by the frame. theres also rust on the inside bend of the pipe where its only noticeable from a certain angle, so i decided a while ago that i was being a fussy bastard and that id leave it be, but on wednesday i changed my mind and thought id have a crack at it anyway.

these pictures are of the pipe as removed from the bike after a wet ride, so its dirty and some of it isnt as bad as it looks in the pics






this however IS exactly as bad as it looks

[Sean91]

got some music on the go, 80s style


i cleaned up the pipe with wd40 to reveal how much is actually 'below the surface' rust. the fat section of the pipe shined up beautifully but there is a lot of rust in the bends that you dont really see in this pic


my tools for the job


you can see all the pitting left behind by the rust but 99% of the oxidisation i managed to remove




£9 quids worth of silver engine paint

[Sean91]

The end result.....


EDIT 11/03/16: The paint i used didnt hold up under the heat of the header, so I'm looking into tougher paint & curing methods, and i'll have another go at it next week

That's impressive!

That's another job to put on my list!

[jompy]

Nice one mate looks good
Aren't you a tad young to be owning an 80's Mega Blaster ?
Makita cordless stick battery drill you don't see those often these days , I found them really cumbersome & unbalanced but they last forever , you can still get batteries for them from pattern companies !

i spoke to the Mr's and she says the BT090's are a good tyre they're are old now a , she recommends the conti attack SM's but seem a bit pricey to me at around the £190 mark but thats the same as the bt090's on stickystuff https://www.motorcycletyresandaccessori ... -tyre.html
i had a pair of conti attack SM's and they seemed good but don't bother with the Goldspeed/maxxis they're a bit hard .

Dunlop alpha 13's are supposed to be tyre of choice for lighter bikes. They've been available in Australasia for a couple of years but have just started importing them into the UK.

thanks for the info on the tyres, i was thinking if i change them then id like something with more grip when im not on the road because i have a lot of lanes and loose dirt around by me and the battlax's have nil grip on that. im not thinking those nobbly supermoto tyres you can get but at least something with more of a grippy tread pattern that dont leave me wheel spinning

@jompy: Apparently they was one of the very first cordless drills, my dad said he had one when he worked fitting bedrooms in the 80s. i got mine from cash converters for 15quid barely used and in the original metal case with original charger. the battery aint so good anymore though.

and yeah you're right, i wasnt doing any breakdancing in the 80s but i actually have two vintage 'ghettoblasters' the circa '83 sharp gf you see on the last page and an '88 hitachi 3d. they're great for when your working on something outside and they're loud as fook! but if theres no sockets around, the amount of batteries they go through is ridiculous...
I bought both as non working projects when i was 18, hitachi was an easy fix, needed a new plug, a good clean and i had to repaint the case. But the sharp took over a year to restore, literally nothing on it worked, even needed new speakers.
