I would like to say hello to everyone And I need a little help. I have a 2007 Road King with a 96" engine. I installed a Woods TW6-6 cam with a +4 gear. When I raise throttle from idle to around 2000 rpm I get a popping out of the exhaust on the front cylinder.It will not do it all the time. Any help would be nice.

I would suggest you get the bike tuned by a competent tuner.

Dont do any riding until you get that tuned.

I realize this may be a little too late but... I hope you have done your research on that tuner. Lots of guys call themselves tuners & will take your money, few actually know how to do it right and will take the time to do it right.

The tuner I'am going see is ok. I used him 2 years ago.

mike cats? he is a good tuner. and knows woods stuff well.

bigbluff · 10-09-2009, 11:57 PM

Ummm... is it possible the front cam is a tooth off in timing?

jumiem · 10-10-2009, 07:49 AM

You may be right . I will pull it apart too check it.

does it hiccup then pop? if so it is lean in that area.
no way around buying a tuning device and tuning it with that set up.

Sorry it took so long to reply,but I will start from the the top again. I have a o7 with 96 engine,se air cleaner,vh true duals,vh oval mufflers and commander.I had it tuned and it was 75.88 power & 93.42 torque. I installed a Woods TW6-6 cam And a +4 gear. Now it was tuned by the same guy and it shows 72.17 power and 92.27 torque. he said the mufflers are the trouble.Maybe I have to much cam.It pulls from 2000rpm to 4000rpm and stops at 72 hp and stay flat to 5500 rpm.

So if I read this correctly the cam/advance gear setup actually lost power?, how do the torque curves compare? Would be interesting to see the difference with a decent exhaust, chances are the stock head pipes and cheap slip- ons would perform better.

I went through something similar with my 54h cams and found out it was the lifters giving up. I had my motor torn down twice by two Harley dealers trying to fix my crank cases leaking oil and they both missed the bad lifters.

jumiem · 11-14-2009, 03:33 PM

These are new lifters I installed with the cams.
