DT125R FORUM

Merry Christmas everyone!

@HOTSHOT-III Hopefully the issue gets resolved as I don't want to lose the data they're hosting. The important stuff I ought to host here to guarantee it isn't lost.

@madmackie No worries If you get the P45T bulb in the link it should fit straight into the light/wiring, P45T fitting is similar to the more common H4 but not identical. I don't know of any other Yamaha that uses P45T bulb fitting but every DTR I've ever owned has had it. Copied and pasted from Google AI Overview: P45T and H4 are both dual-filament (high/low beam) headlight bulbs, but they differ primarily in their base diameter and application. P45T features a large 45mm round base often found on older classic vehicles, while H4 (specifically P43T) has a smaller 43mm base standard on modern cars. Key Differences: Base Diameter: P45T is 45mm; H4 (P43T) is 43mm. Application: P45T is used for older, vintage European cars and motorcycles. H4 is for modern vehicles. Interchangeability: They are not directly interchangeable, but adapters exist to fit H4 bulbs into P45T housings. Performance: Both come in halogen, but H4 is more commonly found in higher-wattage, brighter variants. Summary Table Feature P45T (R2/H5) H4 (P43T) Base Shape Large Round Smaller Round/Triangle Base Diameter 45mm 43mm Vehicle Age Classic/Vintage Modern Availability Harder to find Ubiquitous

Hello @chalcosoma, Apologise I didn't get around to replying last night. You can get away with running some pretty aggressive tyres on the stock rims, my friend once went very savage on his DTR (to the point spokes to breaking left right and center ). Sadly, I am not that clued up on tyres and availability in the States in general, but I certainly would have thought this wouldn't be a hard problem to solve. It would be interesting to hear what other people have run in the past as I know quite a few members had TDRs.

Not familiar with a 1994 DT175 (I presume this is from the Asia (Far East) market). The oil light will just be for the two stroke. There are no sensors that do gearbox, the most you get is a Neutral Light sensor (if you're lucky). For the gearbox oil, the only sensors you see are with your eye balls and the oil sight glass. I can't 100% say this is the case, but I say it with high confidence that this will be the case. Hopefully that's useful. Calum

Hi, thanks again for the detailed reply and for all the information. I had already heard about the larger snorkel from the DT200/DT230, but I’ve seen that they are very difficult to find. Designing one in CAD could be possible, but I don’t have any experience with CAD programs and I also don’t have access to a 3D printer. Regarding the carbon reeds, I had heard about them before but I’m not sure which ones would be a good option at a reasonable price. I’ve also read that some people install a VForce4 reed block for the Yamaha Blaster on the DT125 with small modifications. However, it’s quite expensive. I did find a cheap copy on AliExpress, but I’m worried that the lower quality materials could damage the engine or even perform worse than the original reed block. The air filter was replaced a few months ago with a TwinAir filter, and the exhaust was also cleaned a few months ago. If I eventually decide to modify those spigots in the inlet port, do you know where I could find a good guide or tutorial to follow?

@Calum That site is known even more year's!!!!!
