Re: ST1300 (Air Box) Base Funnel Screws - Fix

byron your an angel and master of the st, I can never get over how much help you guys are here, I took my airbox off this morning to see if somehting was wrong, I installed the ccs-100 amonth or so ago and my throttle cable had gotten a little extra play in it, so I went in to investigate and found that it must of streched a little, maybe I,m twisting it to hard LOL,, the ccs was still in good standing, Of coourse I stripped one screw the first time and another the second time I disassembled the airbox, so what will I do, get the screws and shims and washers from the local home depot like described here, great help and thanks a million, this bike is getting easier to work on more and more, I will get a torque wrench soon, any suggestions

t-bone,

I'm curious about your statement, "1 minute epoxy will fix mine". Are you talking about using it on the newly made allen screw setup or are you talking about fixing a stripped phlilips head?

The 1100 was the same way. I just slotted a stubborn screw, and took it out with a flat blade, no problem. Honda must loctite all their fasteners in and around carbs/TB's. Makes sense. You can see why they made that screw 1 pc., after dropping spacer into TB.

Re: ST1300-Base Funnel Screws (Air Box) Fix

I have been wanting to make some of these but can't seem to source the spacers anywhere locally. I have tried Lowes and Ace Hardware. They have steel and nylon but no aluminum. The best they have had was about 3' of aluminum tubing that I could cut down but that was $10 and more than I need. I found some online. I may have to place an order somewhere.

Re: ST1300-Base Funnel Screws (Air Box) Fix

I just installed my TCI61# FPR , and I agree phillips heads are not the best choice. I was lucky, P2 12" phillips, downward pressure and twist, broke all free, but 1 did get one a little skewed..It installed back solid though. Good article. For those who want a possible plug and play type solution.. check fastenal http://www.fastenal.com/web/products/detail.ex?sku=0154418. I was matching up using the supplied measurements in the article.See under Product details ...Excellent article and write up.

Re: ST1300-Base Funnel Screws (Air Box) Fix

I have two cents to add. I have always had good luck using the phillips screw bits meant for drywall screws. My BIL is a drywaller and he gets his bits for the screw gun from the contractor supplier. They are very, very hard metal and shaped slightly different than your average Phillips #2. They really bite well and when they get the slightest bit worn you throw it away and get new one. If you know you're going to be working on something with questionable quality phillips head screws run out and get a few of these bits. In this case, I think these OEM screws in question are made of lead-loy and very easy to strip so you might only have one chance to get them out.

Good Article!

Or you can be lucky and they are all loose.

JIS screwdrivers are also available at McMaster-Carr. The JIS screws generally won't strip out if loosened with a JIS driver...

One thing that makes the hex bolts an improvement over the JIS screws is that if you're not carrying a JIS screwdriver, hex keys are much easier to find if you need one.

Norm reccomends dipping the tip of a screwdriver into valve lapping compound to help it grip the head of a questionable screw.

stuck air box screws extracted to free up idle speed screw

The 8 (JIS head, 5mm) bolts that hold the air box to the throttle body, were seized, but I removed 4 of them, with WD40 and a VERSA, JIS impact screwdriver.

The 4 screws that were not budging, I used a very clever extractor called "pro-grabbit"

http://prograbit.com/Pages/grabitPro.php

it looks like a cordless drill bit. It has a LEFT hand drill bit with shelf stop on one side, then flip the bit over, it has the correct size screw extractor bit the other side.
into a cordless drill, Left - couterclockwise, slow drilling and within 10 seconds, it grabs the stubborn bolt out!

Dont forget to block the throttle bores gently with clean rags, to protect metalic shards and mishaps...

I replaced all 8 bolts with Alan, 5mm x 20mm, added flat washers, lock washers and anti-seize paste on the threads.

A three second spray of WD40 onto the idle speed assembly (left side of throttle bodies, just follow the adjuster cable to the pivot assembly, between cylinder #1 and #4) and what has been a very stuck, immobile idle adjustment screw, now moves freely and can be easily adjusted.

2 hours work all up. Just need to remember to rotate the idle screw a bit every month or so, to prevent it from getting stuck again!

hope this is usefull for anyone with same issue.

good luck​

Ciao,
I wish this were so. I used only a JIS screwdriver to remove the screws to my airbox. Alas, the very last screw head stripped with very light force. Since I didn't have the time or parts to R&R the fuel tank I replaced all of the screws and am now waiting for my next scheduled maintenance to fix it. :)
