Since I’ve had the ‘new’ radiator on I’ve had a lot better temps during the hot days recently. I’ve swapped out the standard tailpipe for a BigOne that’s been laying around, this seems to be beneficial as well. It seems to be running even cooler. Not sure why...

The plugs been dry since I fitted the 17.5 pilot jet, the midrange seems good as well going by the plug. Top end/main jet is still buggered. The last two times I snapped the throttle open fully I had heatseize symptoms. Both times I whipped the clutch in and coasted to a stop, both times it started up straight away. I haven’t been in a position to recreate the symptoms to see if it was a genuine heat seazure (sp?) or a totall bogout due to main jet being wrong. It’s a 210 ATM, it was a 180 before...

Problem on top of problem after problem being an invisible problem 🤯

Oh well it’s all in fun and we live and learn while the World falls apart around us! 😜

I'm not sure if this is still FS but hey what an investment;

@lorant2
Was that after the wobble started?

@spookdog okay mate thank you , will have a play with it

That looks like amazing fun.

@rking7888 the 125x/re are very similar to the 230 with a few changes like ally swingarm, twin rads, headlight etc. I think that the 230 is the top of the range if you like

Regarding the frames the dt200wr was meant to be a soft-enduro and so the frame is borrowed (not 100%) from the yz's where as the 125/230 is a trail bike and used the dt frame from around '88 with only minor mods across its life span

@rking7888 not sure tbh as they are different so no idea how close they are for this type of fit

You could always make some yourself from some 3mm (or similar) aluminium sheet and attach to the rear brake MC bolts

@nottsbiker yeah would be a fun bike

@madgyver Yeah that looks mint to be fair. Done a great job on that.

Jeez, it's possible that the the bolts seized into the aluminium. Dissimilar metals and all that. That said should still be easy to remove the bolts. The aluminium case will expand when heat is applied so should be simple to disassemble.

Yes the pump pulls off the shaft so long as you've disconnected the oil lines and cables etc.

For the carb use 0.5mm gasket paper and be very careful to the details.

From memory;

DT200R 3ET - front and rear
DT200WR or WR200 - rear only
DT125RE - front and rear

Personally I'd refurb my hubs and have SS spokes laced into alloy rims

@madgyver said in Carb warming hose delete:

@declan I have done exactly what you say.No problem so far in the summer,for the winter probably will be the same status.

Blanked off this in every two stroke Yamaha I've ever owned and never had any problems, but have had a BWS carb ice and that made for an interesting ride 😉

@spookdog @Calum Found it!, i found a break in the kill switch wire in the middle of the loom! Not sure how it was broken but it was obviously breaking the circuit. As soon as i sorted that it fired straight up. Many thanks for all the ideas and help. very useful.

@dan28 yeah I did it as I said the blaster 200 are a better fit the cr 125 ones are a little too small but you can make them work

@waale2004
Check your plug colour. I’m guessing you are running rich with a wet black plug. Cause at 50:1 all your oil is being burnt/used. It can only be excess fuel...

@waale2004

You changed the seal as well as the o~rings. I don’t know if the Athena kit uses special or standard parts? 2 o~rings & 1 bush seal. These are the only parts that can be a problem...

Do you premix 50:1?...
