I have YFS200 blaster vforce4 in my DT175/225MX, they just fit straight in bike has a stroker blaster crank blaster topend, i think they would be a bit narrow for a dtr. Wr200 might fit with a bit of moding. I have a DTR/YZ 125 engine running standard reeds with one and a quarter sets of petals to prevent high rpm flutter. Modded yz inlet rubber just to bolt holes need drilling and a bit trimmed off the right hand side, a modded open top dtr airbox with yz carb to airbox rubber with yz carb runs great

@glynn123 The thermostat provides several features. And the one you're referring to is the less significant one.

Yes the thermostat allows for quicker warming up of the engine, prevention of a heat seizure when the radiator dissipates too much heat, but that is only part of the story.

The thermostat also acts as an intentional resistor in the water jacket. It will prevent stale, localised boiling, of coolant within the jacket, by pressursing the water. Thus the exchange of coolant is made causing any boiled pockets of gas to be moved on and either vented out through the radiator cap, or through the rest of the cooling system.

This feature stops the cylinder distorting, or more importantly, the cylinder head, where most the heat will occur.

Its not that i want to use it - i will buy another tm28ss and have it enlarged when money is on my side next month.
As i wish to get my barrel bored sleeved and enlarged too.

The WR 426 fork swap I done wasnt too bad, itd be even easier using a WR 426 wheel or hub aswell, also if you got SM rims laced to a WR 426 front hub you could use standard WR axle, caliper and just buy a 320mm caliper adapter to suit the full size SM disc. I was too cheap for this so made my own axle and caliper bracket to run standard DTX wheel, speedo drive and get the 426 caliper to work on the 300mm DTX disc haha.

my problem was jetting now rev cleaner through all gears I just lost my head as the problem started a few days before new pipe must have been the old pipe getting too bad stupid of me changed jetting now on a 250 main still not were I want her to be the needle is a bit rich just waiting on a few jets arriving

Looking lovely, I'd be reluctant to bend the pipe, just make up a larger bracket and move it closer.

Think got the hang of it now. 0_1518154039669_b.jpg

@oldman Personally I would return the damaged one straight away.

Decided to change the seat cover this afternoon before work, also reshaped it so it fits the MX fender more natural & installed my trail tech in my bar pad.

Trailtech vapor, not sure how to overcome the crinkle of the pad tape

@oldman

Glad she's arrived safely Paul, enjoy her she's a beautiful old girl

@andrewj1680 I know it's common fouled plugs on crossers that simply once there is heat in the combustion chamber that it they start.

@tdrgreg2 Looks damn good to me dude, very motocrossy I must say. Top job :thumbsup_tone3:
