Today I have decided to do the big bore. I will be going with the JE 13:1 1397cc piston kit. Currently have the crank being stroked for an additional 112cc. Now my question is...will the stock fuel pump be enough to power that engine?
NO you will be fine... However in a hot climate i would put on a second fan or a fan you can turn on and off. i have not put the second fan on but could use it in traffic.Your point brings up another. Since the bigger engine puts out more heat, will the radiator have to be supersized too?
Curious in California.
Car and bike fuel pump are the same thing. For performance you need a whole lot of gas. It keeps the pump running steady. about $250.00-$280.00Err...WTFudge!! Is this thing (T-Rex) a freakin car fuel pump? How long does a tank of gas last? And realize this isn't a drag bike at all. How much did the pump cost you?
As long as you don't use NOS or turbo you will be fine. If you go lean a little.Can the pump be adjusted? With a pump like this can I squeeze out at least 175 miles per tank of gas? Or does that not matter because it depends on the mapping from the pc2? This project is starting to scare me. Here in Japan just less than 6 gallons of gas costs $15-19 dollars.
What will my engine tell me if I stayed with the stock pump vs. the aftermarket? Will it half ass accelerate? Will the engine even start? Lets say it started and ran just fine...is there anyway it can damage the engine for not having enough fuel?
Where to buy and what model?
That is a heffty engine. I would go with a high volume pump like the T-Rex. There are others that will work well also. You can try the stock and if it craps out you know what the problem will be.Ok...I'm chaning it more than ya'll know. The 5mm stroke and the 1397cc pistons comes to 1507cc. This is from the bore x bore x stroke x .7854 = blah blah x 4. Learned that last night! yeah baby. So will this require that T-Rex fuel pump?
Alright thank you very much for any info that ya'll can give.
SearchWhat exactly do you mean crap out? What is the worst that can happen? That is what I need to know so I don't blow anything up. I'm worried about stuff like that you know. I haven't riddin' since Jan. Once its back together and right I don't want to have anymore down time like this EVER again!
If the engine just stops running...not to bad...just where, that can be the serious problem...hehe
But if something could break...we got serious issues to worry about.
Also WHERE can I buy this pump from? What model number? How much PSI? You know...alittle more info on this pump please so I can get my research on.
Thanks like always bro!
