I need a little more guidence as I am getting overwhelmed with my options...[sm=confused06.gif]


After some thought process, I have decided to NOT do a build on my RG that will require case boring or clutch work. I want as much pull as I can get without rebuilding the whole thing. I spoke with a local independent shop yesterday. One of the guys worked for HD for about 8 years and then spent some time with Kendal Johnson. They are familiar with and like Head Quarters products, use T-Man for their machine work, like to use the Power Commander for fuel management and got excited when I asked how they felt about the D&D Fat Cat. They also referenced using S&S products as well.

I explained that I was not interested in 100mph speeds or riding wheelies from here to Texas. I told them that I did want a seat of the pants *** gripping pull from 0 to 80 in a motor that was dependable. They replied with a smile that they needed to build a strong torque motor for me and referenced a 103 build with cams and headwork to achieve this.

I am supposed to go sit down with them this weekend and put some ideas together and get some pricing. I want to post what they recommend and get some feed back from you motor gurus to be sure I am not going down the wrong path.

I am kind of thinking a HQ 103, pistons if needed (?), fat cat, power commander, good flow intake, larger throttle body if needed (?), EVO 30 tooth sprocket and all the other misc stuff to put it together.

If I need any education before I speak with them please feel free to provide it. I plan on going sometime tomorrow and I will post the build for feedback before I commit. Thanks for being patient with your advice and if I am expecting too much out of the 103, please speak now. I can take all kinds of criticism as long as you educate me.

Thanks in advance for taking your time to assist me in spnding more money...

I have the HQ-103ST I have a little more tuning to go but it is coming along real nice. I haven't tried a wheelie yet but I know it will do one.The one thing I will tell you, and if you look under Philm caption is says it all" ALWAYS use components that COMPLEMENT one another! " You don't want to mix and match. JMHO. Rick

 

Done right, you will be VERY happy with a 103 (or 107 using bored, stock cylinders). The HQ 103 or 107 Touring or Sport Touring pkg w/575 cams will not disappoint!

I'd suggest giving Kevin or Doug a call @ Head-Quarters. They will help ya make sure you have everything "just right" and your indy will be ready to go to town. For either of these builds, you will not need a larger TB ~ actually you will get better results (in useable power range) with the stocker. THe 08's a pretty big to start with.

A FatCat will work great on that build. The only thing I'd be curious about is a PCIII vs SERT or something else...???...

Feel free to PM me if I can help ya figure anything out....

 

Joe, are you expecting the indy to "assemble" a motor for you or "design" a motor for you?

I ask because it's very easy to order an HQ 103 that is a reliable and powerful engine that delivers 40+ mpg, and find a competent engine assembler to put it together for you. Lot's of guys have built this package themselves or had it assembled/installed for them and I've yet to read that they were dissappointed with their choice--except for the guys who wished they had built a 113 or 120 instead of a 103. And it will come with larger diameter pistons--any 103 will require larger diameter pistons since you are increasing displacement without increasing stroke.

Your '08 comes with a 50 mm throttle body; you don't need a larger throttle body for the build you are considering.

On the other hand, if youare meeting with an indy with the idea that they will design and engine for you (i.e. select pistons, head work, cams, etc.) then good luck--hope they know what they're doing (many don't).

Also understand the economics of an indy shop--you could buy an HQ package direct from HQ, pay a core charge so your bike isn't down while the heads and cylinders are being machined, recover the core charge after your build is complete and you return your take-off heads and cylinders to HQ, and the indy makes money only on the labor of installing the HQ package. However, if the indy sells you someone else's headwork, cams, push rods, lifters, a larger throttle body, etc., they make money on the mark-up between the dealer/distributor/wholesaleprice they payand the retail price they charge you--in addition to the labor charge. That's not a criticism of the indy, just saying that there is a financial incentive to sell you components from other vendors rather than just the labor of installing a package that you purchased direct from HQ or an equivalent vendor. And there is an incentive to upsell you items you don't need, like a larger throttle body and roller rockers being the most common.

Good luck with your research.

 

I believe by the statements made, my meeting with the INDY should be to get a quote on assembling the build that I put together with the research done on here and after I call Doug at HQ which makes perfect sense. I have two more questions...

Phill, you mentioned a 103 or 107 build... Can I do a 107 without doing the case boring? If so, that is the way I will go and I will also do whatever Doug recomends for the fuel managment.

With this build, would you guys do the 30 tooth sprocket as well?

Thanks, Joe

 

Yes, you can do the 107 without case bore. There are two option for getting to the 107. One uses the RevPerf Nikasil jugs and pistons that come from RevPerf as a "kit". The other is to request that Doug bores your (or core swap) cylinders to appropriate size for the 107". Boring to 107 is relatively new and you'll have to specifically request it, but there is one huge advantage to this method. That is the fact that Doug can bore the cylinders to specificly fit (match) the pistons. With the RevPerf solution, they come coated and can not be modified at that point by anyone except RevPerf. Not to mention the $$$ savings (roughly $500).

Check with Dalton on the compensator sprocket. I do believe it will significanly improve your gear ratios and improve low-end acceleration. You said no interest in wheelies or burnouts... so be careful... they will "just happen" ...

Be patient trying to get Doug or Kevin on the line. You may have to leave a message, but they WILL call you back. As I said... holler if I can help.

 

Phil meant to say "Yes you can do the 107 without case bore"[8D]

 

Joe, apologies to you if I misread your original post--references to T-Man machining and S&S threw me a curve since there isn't any machining involved in installing the HQ 103/107 kits which will come with HQ cams; probably the 575.

You could shoot bigjohn1percenter a PM; he built an HQ 107 using stock cylinders bored by Doug at HQ and matching pistonsinstead of the RevPerf nikasil cylinders/pistons.

Good luck with your build and research.

 

go big---do the HQs 107 no case boring required -- I would have done this if it was option when I got my HQs 103.

Like others have said give them a call -- they will be more than willing to talk motors with you.

 

I just did a 103 on my 08 I didn't do any head work and got real good power results

anyway with the 08's there is no core charge option as most shops don't have any 08 heads sitting on there shelves so if you do head work on your 08 expect it to be down atleast 2-3weeeks (The 08 heads are diff then 07) but well worth it i guess so they say.

I talked with alot of indys and the best thing or advice I asked other riders wheres there a good indy and went and talked with a few of them in my area and you will know when you talk with that person whats up like harleypingman said most of them don't know much about the 08's.

Good Luck

you will love your new scoot when it's done
