resistor plug for 79 predator?

[shwnrttr]

anybody know what resistor plug will work in my 79cc predator. the stock one is a E5TC Torch.

[shwnrttr]

every plug i cross refference with the stock one is too long. should i just shim it or can i find the right size plug?

[LabRat]

forget but its same as some old chevys

The resistor version of your plug is E5RTC

IMO, you should get an NGK instead. The cross-reference for that is BPR5HS (6222).

According to my research they all have the same reach. The old Greyhound 79 and Pred 99 took the same plug as yours, albeit with different heat ranges.

I use an NGK iridium plug in my predator 99cc. BPR6HIX is the colder months and the BPR7HIX in the hot months. I'd rather use a BPR5HIX in the colder months but nobody ever seems to have that plug locally or online. If you live in Florida, then I'd opt for the 7 because you live in a sub-tropical state. Sick bike parts sells most of the plugs related to these motors.

thanks. the cross reference site i was using told me NGK BPR5ES.but those where too long. i guess the ES has longer threads

I have the same engine, and I'm interested in anything about it. But my understanding is that a resistor plug's advantage is that it produces less radio frequency interference (RFI). Is that why you want one?

[shwnrttr]

yes. when i start the engine it resets my speedo. hoping the resistor plug will fix that. still havent picked one up yet. been too busy.
