The magnetic oil drain plug from JMP (M12 x 1.50 mm, 15 mm, aluminum racing, black) makes a very high-quality impression. The workmanship is top-notch, the aluminium looks stable and cleanly anodized, and the magnet at the tip sits firmly and strongly - just as you would expect from a racing part. Especially with regular maintenance or an ambitious driving style, a magnet like this is really useful for detecting metal abrasion in the oil at an early stage and preventing damage.
The screw would have fitted perfectly on my Yamaha MT-03 (built in 2016) - thread fits, length fits, everything is great.
Unfortunately, I still had to return it because no sealing ring was supplied. Although this is not misrepresented in the item description, I honestly expected a suitable copper or aluminum sealing ring to be included with such a product - especially because it is a safety-relevant part and most other suppliers supply the ring directly. Without a suitable sealing ring, I would either have had to improvise or order an extra one.
Conclusion: Top quality, looks great, magnetic function very useful - but make sure when buying that no sealing ring is included. If you order one separately or still have one at home, the screw is highly recommended!
Coil used in 1992 Yamaha dt 80 lc2.The coil creates a very strong spark without any problem, yamaszka smokes from the kick. It perfectly harmonizes with the author's ignition module. The quality of workmanship is not objectionable. The silicone cap fits perfectly on the plug,and the core of the high-voltage wire is not thin compared to others.
So far I am very impressed when it comes to the quality of parts produced by Naraku, this will certainly not be the last product I buy from this company.
