| | Posted : 06 Dec 2023 - 01:46 Post title : Thunderbird 1700 Big Bore Cam | | | There's a rumor the '09-'10 big bore cam is different, it appears true looking at RPM numbers. And note the Storm is 1699cc, not 1700. ...I'll take all I can get

| | Posted : 07 Dec 2023 - 19:52 Post title : Re: Thunderbird 1700 Big Bore Cam (Re: Leethal) | | | When i got my BB installed, i had it done by mickey cohen who a the time (maybe stil is, i dunno) was the USA fleet mech for triumph. He was quite adamant that the BB cams were hotter than the stock 1700 cams. He is also a custom builder and racer and knows engines of all kinds in and out let alone triumph. So true or not i guess we will never know, but that guy is probably the most in the know triumph associate of any kind in the USA so i tend to believe him more than not.

When Indian were doing stage upgrades they came with a tune relevant to each stage.

Good point. I'm curious too so i just emailed Mickey and i will post his answer if and when he replies. He can be pretty dismissive when asked questions that piss him off so i don't now if he will reply considering asking this appears to question his authority. I asked him if the BB cams are hotter like you once told me, why are there not separate tunes for the factory 1700s and the BB kit? I worded it a bit different to try and not sound like i was questioning his authority but we'll have to wait and see what he says.

| | Posted : 09 Dec 2023 Post title : Re: Thunderbird 1700 Big Bore Cam (Re: Leethal) | | | Well, i hope you can make more sense of his reply than me because i have no idea what he said...
The 1700 comes with bigger cams. There is no hope up cam. The 1600 got the big bore kit with cams and tune  
I emailed him back to try and clarify what i was asking. I'll post back if and when he replies again.

| | Posted : 09 Dec 2023 - 04:46 Post title : Re: Thunderbird 1700 Big Bore Cam | | | Wow, i dunno if he just found out he was wrong at some point or I misunderstood him or what, but at some point he did say the BB cams were hotter. Maybe he thought i was asking as compared to the 1600? Actually, come to think of it i don't think i even asked, i think he volunteered that info. I dunno. But this was what....12 years ago i guess. Anyways, he replied to my second email as follows, so looks like the 1700 factory bikes have the same cams as the BB.
Me: so are u saying the big bore kit cams are the same cams that come in the storm?
Yes

| | Posted : 09 Dec 2023 - 17:57 Post title : Re: Thunderbird 1700 Big Bore Cam (Re: Leethal) | | | this hotter cam was all beat to death years ago, there is a long thread about somewhere.
I did the BB cam swap on my 1600 (in 2010) and later compared the factory part numbers for the BB cams and the later 1700 cams, same part numbers.
I use the tunes for the 1700 motors.
