Hi Big Dan It's a '75-'76 (model 152) Frontera mk. 9 250cc, according to this page: https://cemoto.tripod.com/bultaco.htm Will send a PM Regards

I have used petrol mixed 50/50 with lacquer thinners or, neat lacquer thinners. Let it stand for a while and slosh it around every now and then. You will see it working as the (clear) thinners takes on the colour of the gunk it is dissolving. Regards

Contact a friend of mine: Richard Yamane, via Facebook. He's in the USA and works on a range of classic bikes. He should know who can help you with a sprocket. https://www.facebook.com/richard.yamane.7

PMK, that's a very nice and special bike. RT360 is a good motor. Well done!

Interesting looking silencer that! Nice Lotus too!

Thanks Larry!

Is that the Ormstown Vintage Fest? If so, I was there in 2016, invited by Helmut Clasen who was competing in the Cross Country. I was working in Montreal and took a trip out there for the weekend. I met Mick Andrews, but I missed the trials event. David

Thanks Larry s.k. and motovita Thanks for the replies. Yes, they sold thousands of those in the early '70s, especially in the US. Every now and again, one pops up here in the UK. I'm looking for one to finish a project... Enjoy your Hodaka, you can make those things fly! Regards

I have a slightly OT question: Do you know what brand that universal plastic tank is?

I do as feetupfun said, using paraffin. After drying out, I still give the dry filter a good beating on my hand to dislodge any last bits of dust.

Looks very Cheetah-esque, but enough details are different to suggest it's something else, or even an earlier/later Cheetah development. Maybe Mick Whitlock could be contacted to ask? Does it have a frame number?

Yes it is.

I gave this some thought when doing the conversion but as as my bike is a '68 (post- '65 design), it wouldn't be eligible for pre - '65 anyway. Then, on a purely practical basis, the Yamaha YDS3 carb is, at latest, off a '67 bike so it's older than my bike!

I've fitted a Mikuni carb to my Villiers 37A, to replace the Villiers S25 carb. Must be a 24 or 26mm - came off a mid'60's Yamaha YDS3 and it went in with a small amount of adapting, as well as just a slightly larger pilot jet and main jet. After years of messing around with difficult starting with the Villiers carb, the Mikuni gives starts from cold in 2-3 kicks, plus first kick hot starts, good idling and no dribbling. Just a better carb.
