Surely the reason people fitted carbs in that instance is because it was easier than fitting a new/spliced wiring loom to accomodate?
I don't really understand this anti 4RT mentality, plucking random figures out of the air for imaginary parts.
Yes it's dearer than a 2 stroke, yes it's more complicated, yes some people think it's over engineered to the point of being too big. Surely the point is this, if you like it buy it, if you don't, well don't and go buy something that you do like, there's plenty out there! If you think that "some black box" will break costing
so I don't know if the fittings are stock or not without looking at another 4rt
Yes, that's the same MC as fitted to the 315, it's a straight swap job including lever, the hose is exactly the same.
does the old 315 master sort the on off clutch or another brand??
what have you fitted???
is the hydraulic hose fitting the same thread size on most trialers,ajp seem to make most of the components
Just fitted the larger MC and it definitely gives a smoother more progressive action but doesn't totally eliminate drag, or at least it hasn't on mine. like I said above the hose is interchangeable.
Get yourself to any decent outdoor/walking shop and have a look at a Multifuel flask. Sigg and MSR are the 2 that I've used without any problems. Not cheap but quality bits of kit that don't leak and are pretty tough. I haven't used one in the Scottish though, because it's not allowed
Forgive me if you think I'm speaking out of turn but isn't advertising your bike for sale within the forums as part of your signature a little hypocritical? I was under the impression that this is what the Classified Ads was for?
Has anyone got any tips on oil and filter change!When i take the casing off its hanging from cables,and the gasket needs cleaning off.to me this is putting strain on the cables,twisting and pulling.Also bits of the gasket need cleaning from the casing.Just wondered what other 4rt owners do?
If you read the manual again it tells you where to disconnect the ignition cable at a plug near the rear brake reservoir. I missed it aswell on my first oil change and thought it was a bit gash on Honda's part, so I re read the maunual and all was revealed. Simple enough job though.
The French 4 day caters for every class of rider from Experts which is probably Euro round standard down to beginner and everything in between.
It's all pretty relaxed with no time limit. It's usually one lap on Thursday then two laps thereafter or you can choose just to do one lap, they're quite long laps resulting in long days!
In summary it's a great event in the sun, with cheap beer/even cheaper wine and BBQ's all week!
Unless I'm mistaken, Dougie rode a standard bike for the Scott with a few trick bits on, not the full titanium works jobbie. The pics seem to back this up ie no handmade fat black hubs etc.
No doubt I await the usual barrage of " the works Mont is this, that and the other"
Dougie rode Laia's SSDT bike in the Scott. There was much ribbing about "riding a girl's bike"
Ah well I was half mistaken! Nothing new there then!
multi world champ on a hand built titanium bike... would have been a disaster if he hadn't have done well!!!

Does anyone know where in the UK that might stock or be able to order the 2007 RTL250F plastics. They are similar to the Fujigas Rep ones in white. Just fancy having something a bit different.
I appreciate that Andy has understandably clamped down on forum advertising so if you don't feel able to post a reply then please PM me.
The exhaust port needs raising quite a lot and widening a touch, I have the required dims somewhere which I'll try and dig out, the later pistons also have shaped crowns. I think I took about about 10mm off the flywheel, again I'd have to check. The inlet tract/manifold was shortened by apprx 12mm which then moves the carb and airbox down and forward, this makes BIG difference especially bottom end. Finally I advanced the ignition 3-4mm. You end up with a quieter, smoother and more poky motor which is far usable in sections. There was a brand new ally kickstart on ebay this week .
I'll try and find all the Dims and PM you with them
Just had a look at both the Bing and Craigy Quarry on Google Maps, the quarry doesn't actually look like a quarry from the images but having ridden there a few times it's got everything from small beginner stuff to full blown World round stuff.
So Koevoet which Bing is the one to go riding at? The one next to the golf course or the one to the south which appears the larger of the two.
Me and a mate from Fife were looking at coming down next weekend to either the Quarry or the bing for a change, although we think there's a Dunfermline club trial on at Knockhill.(can't remember where I saw that)
Fancy a bit more power, Currently have PTB from Sandyfords but that can only take you so far. Need more cubes.
To be honest, it looks like you've answered your own question. You already have a PTB so the 260 kit is only duplicating what you already have, give or take 10 cc's and a sport's cam. So, as there is no real substitute for cubes the 280 seems the way to go! Should go well with your PTB.
As I haven't tried either, this is an opinion based on the info you've provided ie prices and details.
Parts are relatively easy to come by and are still plentiful with exception of spokes. JK hirst and Nigel Birketts are the places to buy along with Trailsbits for universal items like chains, grips, bars,levers etc.
The mod back in the day was to fit a YZ front brake plate with an external brake arm, chamfering the leading edge of the shoes in the standard set up normally helped too.
I do have a YZ front brake plate, PM me if your interested.
Simple enough job though.
