Aircooled Monoshocks

It's a 1984 TY 250 mono. It's got the shock with the remote reservoir. I've taken the preload to the max and wound the spring to it's tightest setting with the two locking rings. The back end bottoms out far too easily - I'm about 100kg with all my gear on. Is there anything else I can do? Does anyone do a heavy duty spring? Should I put a packer in front of the lock rings so they compress existing spring more? My guess is I'll lose some travel but it might be worth it? Should I lay off the beer and pies to lose a few kg's (I think this has to be a very last resort)? Any advice greatly appreciated.

I have a 92 pinky mono, the rim on the rear wheel is badly corroded on the inside, as Z spokes are hard to get I want to get another wheel but with traditional spokes. Talon have their own TY hubs(using trad spokes) and could build a wheel for me, the problem is that they are unsure if it would fit the pinky. Are TY wheels interchangeable regardless of whether it's an old TY hub or a new pinky hub? thanks.

Does anyone know the offset measurements for a TY 250 Mono rear wheel (drum brake)?

Hi, I am currently rebuilding a TYMono that has been paired to a Rushton Chair. Its a full strip down, powder coat, replace all bearings etc. It has been converted to a twin shock on the back end which I prefer for the chair use. A few loose ends I am hoping to box out whilst the frame is off being coated: 1) Does anyone know any UK retailers who do front fork springs. TY Trials, SM and InMotion don't seem to list them and the Magicals website said it was going to be back up on 1 Sept but is still down 2) Has anyone replaced the expensive/moulded rear mudguard with a stock replacement available from the sites above. I am pairing the bike with a shedworks tank and seat …

Been noticing that there are a few after market shocks available for the TY250R. Rock shocks, Hagon and now even an Ohlins unit from CTC. Anyone fitted any of these and come to any conclusions on them? My original shock is okay so I'm not needing a replacement, just wondering about whether the performance is much better and what the weight saving is. Cheers Hoodie.

Hi all. Just wondering what year they stopped making twinshocks and started making aircooled mono's. Or did the 2 types overlap for a while?

Are all the cables the same for all air cooled yamaha mono's?

I have a couple broken fins on a Mono cylinder, I'd like to repair them but I'm not sure if the parent material is aluminum or magnesium. I know the side covers are magnesium but not sure about the finned cylinder. If anyone knows which it is, please let me know. Thanks, Jim

Hi All I have a TY250 Mono ( 1985) that has the original foot rests...As they look a bit small and battered I would like to know if there are any replacement pegs that could be used? Looking where the originals are mounted..it seems even if i cut them off, there s minimal space on which to weld after market hangers... Just looking to see if anyone out there has done any mods??? Thanks
