My 280r did the same thing until I changed the plug. Just like you I thought it had a good spark, but a new plug sorted it out. They're really susceptible to the right plug so I always get a couple and keep them handy as mine seems to go through plugs like nobodys business.....
I have recently bought a 1986 KDX200 to tidy up as a bit of a run around I can take into the woods near tthe house I'm moving to.
The bike is already registered but my question is, What are the lighting requirements for a full MOT. I have read through the forums and know it would be easy to get a daytime only MOT, but I reckon it shouldn't be that hard to get the full monty depending on the answers to these questionsr,
- Does the headlight need to have a full AND dipped beam if it did not come as standard? If I need the dip, any suggestions for an aftermarket item that runs on 6v electrics?
- If I go for a full MOT do I need indicators if the bike did not have them as standard?
- Does the brake light need to operate on both brake levers?
Graham Jarvis actually beat Dougie the year they were both in Junior Kickstart together. I remember Dougie seemed a lot more hot headed then than he is now....
I just use motocross gear. I don't want to inflict the sight of me in lycra on anyone!!! Also, the MX gear is much tougher and as there is a much wider range, it is possible to get some good deals. I don't find that it is any more restrictive either.
beta boy is right about the shape of the expansion chamber and it's effect on a power curve.
The harmonics of an exhaust pulse leaving the cylinder are amplified in the expansion chamber to bounce back and forth within it. A shock wave leaving the cyliner helps draw fuel mix through the engine, while a returning shock wave helps seal it ( in the absence of valves) and prevent the unburnt mixture going straight out the exhaust.
the shape of the pipe affects the frequency and amplitude of these shock waves, which in turn affect the way in which fuel is burnt at certain points in the rev range.
Power valves work to alter port height at certain RPM so that tuners can 'have their cake and eat it' so to speak. Certain exhaust port height dimensions work better at high or low revs ( Or in between). A variable exhaust port height allows greater efficiency at a wider rev range.
Sorry if this is basic and doesn't make much sense, but I'm hung over and it's been a long day......
fifth gear wheelie, missed the back brake as the front came back too far, put my foot down and forgot that I can't run as fast as my bike in fifth, promptly pitched forward onto my face and shoulder.....
hands were torn to shreds, not great for a computer programmer.....
A guy here uses a Scorpa long ride in the ulster enduro championship. He recorded a 4th overall in a meeting a couple of weeks ago in the snotty Sperrin forests....
Perfect tool though I reckon taller people might find the going a little cramped on faster sections....
I've read with interest the above posts.. I need a kickstart for a 280R climber
I have tried Rathmel and that guy Culliford and neither have been able to help me find a kickstart for my Climber 280R. I broke it off at the splines collar and lost the broken part in the stream I had stalled in
Rathmell told me point blank that I won't be able to find one so unless someone knows that number of a breaker who does off road stuff I'm a bit screwed.....
It's my first trials bike BA (well apart from a TY80 about 16 years ago.... Now THAT I wish I'd kept) But anyway, yeah I love it. Overweight, too snappy, but it's a conversation piece at trials, pulls like a train and at the mo', I'm the limiting factor on how my results go, so I'll hold onto it until my ability exceeds the bike's or whenever it falls to pieces...
Parts aren't too bad, birkett can get most stuff for the engine.
Only problems I had with mine were on thr first outing the wind was so bad that, not only would the bike not pull more than 4th into the wind, it blew the peak clean off. I hadn't had the centre retaining screw tightened properly. This wasn't even really a fault in the helmet when I think of it.. BVM sorted me out with a new peak for 6 quid in two days.
Oh, and the belt retainer has rusted a bit. Other than that, sound a s a pound. The fitting is good too. My Shark and AGV road helmets are both sz56, a 56 in the Xpeed fitted perfectly as well...
couldn't smell worse than that strawberry siht that made a brief appearance at some of our local trials.... disappeared just as quick as a good curry guff as well....
A guy at the last trial had his scorpa's wheels done black. From a distance they looked really good. It was only when I got up close that I saw he'd used high temp matt black paint without masking off the spokes
Anyway, if you get it done properly I'd say to go for it as the black wheels on the blue bike did look very trick.....
Has anyone ever anodised a frame? Now THAT would be special!!
my thoughts exactly. I was actually pondering this at the bottom of a camber ledge I had just fallen off on saturday as it crumbled under me and my bikes combined titanic mass.
As my Climber lay revving happily on top of my chest and left arm, I pondered how much heavier it seemed than all those pretty little GG's, shercos and betas (note I haven't mentioned Monty's in there, cue flame ).
Anyway, as the exhaust started to singe my left nipple, a moment of clarity arrived. I weigh 115kg's, on top of my climber's ???kg's. Surely a performance gain would be had from me losing some of the bulk that rugby has forced me to gain over the years. Imagine the steps I could climb, the fancy skips and hops I could pull of with my less burdened suspension. The decreased wear on tyres, chains, sprockets, footpegs, the earth's crust etc etc
This struck home as a skinny kid on a TXT200 skipped and bunny hopped his way across what was left of the ledge I had tried to relocate to the bottom of the hill......
